| Single Output UEP Models Ultra-High Density, 2" x 1", 1.2-6 Amp,15-30 Watt DC/DC's FEATURES n PRODUCT OVERVIEW The UEP Series DC/DC Converters deliver the most power/current (up to 30W/6Amps) from a 1" x 2" package. And because of their footprint compatibility, they can be used as drop in replacements for their bigger brothers, the standard 2" x 2" and 1.6" x 2" devices, commonly used in the industry. By combining a high-frequency (340kHz), high-efficiency (to 89%), synchronous-rectifier topology with the newest components and time-tested, fully automated, SMT-on-pcb construction, these UEP Models are able to bring you 15-30W in the standard 2" x 1" package from which most competitors can only get 5-10W. All UEP's deliver their full output power over ambient temperature ranges from -40C to as high as +70C (model and input voltage dependent) without heat sinks or supplemental forced-air cooling. Devices derate to +100C. Output voltages are 3.3, 5, 12 or 15 Volts. Input voltage ranges are 10-18V ("D12" models), 18-36V ("D24" models) or 36-75V ("D48") models. All models feature input pi filters, input undervoltage and overvoltage lockout, input reverse-polarity protection, output overvoltage protection, output current Choice of 3 input ranges: 10-18V, 18-36V, 36-75V Models Include 3.3V @ 4.5A or 6A 5V @ 3.5A or 6A 15V @ 1.2A 12V @ 1.4A Guaranteed efficiencies to 89% 15-30 Watts in 1" x 2" package 340kHz synchronous-rectifier topologies -40 to +60/70C ambient w/o derating Fully isolated (1500Vdc); I/O protected Trim and On/Off Control UL1950/EN60950 certified CE mark (75VIN models) n n n n n n n n n limiting, and continuous short-circuit protection. Standard features also include on/off control and output-trim. All models are certified to IEC950, UL1950 and EN60950 safety requirements for OPERATIONAL insulation. "D48" models (36-75V inputs) are CE marked. UEP Series DC/DC's are packaged in low-cost, light-weight, diallyl phthalate (UL94V-0 rated) plastic packages with standoffs. EMC compliance is achieved via a lownoise design rather than through expensive metal shielding.

See Minimum Output Loading Requirements under Technical Notes. See Technical Notes for details. The On/Off Control is designed to be driven with open-collector logic or the application of appropriate voltages (referenced to -Input (Pin 2)). Applying a voltage to the On/Off Control pin when no input voltage is applied to the converter may cause permanent damage. See Technical Notes. Output noise may be further reduced with the addition of external output capacitors. See Technical Notes. Operating temperature range without derating is model and input-voltage dependent.

Designers will usually use the -Output (pin 5) as the ground/return of the load circuit. You can, however, use the +Output (pin 4) as ground/return to effectively reverse the output polarity. Minimum Output Loading Requirements 3.3 and 5V models employ a synchronous-rectifier design topology. All models regulate within spec and are stable under no-load conditions. 12/15V models employ a traditional forward, diode-rectification architecture and require 25mA loading to achieve their listed regulation specs. Operation under 25mA load conditions will not damage the 12/15V devices; however they may not meet all listed specifications. Filtering and Noise Reduction All UEP Series DC/DC Converters achieve their rated ripple and noise specifications with no external input/output capacitors. In critical applications, input/output noise may be further reduced by installing external I/O caps. Input capacitors should be selected for bulk capacitance, low ESR and high rms-ripple-current ratings. Output capacitors should be selected for low ESR and appropriate frequency response. All caps should have appropriate voltage ratings and be mounted as close to the converters as possible. The most effective combination of external I/O capacitors will be a function of load and layout conditions. Our Applications Engineers can recommend potential solutions and discuss the possibility of our modifying a given device's internal filtering to meet your specific requirements. Contact our Applications Engineering Group for additional details. Input Fusing Certain applications and/or safety agencies may require the installation of fuses at the inputs of power conversion components. Fuses should also be used if the possibility of sustained, non-current-limited, input-voltage polarity reversals exists. For DATEL UEP Series DC/DC Converters, you should use slow-blow type fuses with values no greater than the following.

Adjustments to the output voltage can be accomplished via a trim pot, Figure 2, or a single fixed resistor as shown in Figures 3 and 4. A single fixed resistor can increase or decrease the output voltage depending on its connection. Fixed resistors should have an absolute TCR less than 100ppm/C to minimize sensitivity to changes in temperature. A single resistor connected from the Trim (pin 6) to the +Output (pin 4), see Figure 3, will decrease the output voltage. A resistor connected from the Trim (pin 6) to -Output (pin 5) will increase the output voltage. Trim adjustment greater than 5% can have an adverse effect on the converter's performance and is not recommended. 6.34(VO - 5.714) -49.9 12 - VO 36.23 VO - 12 -49.9 UEP-15/1200-D12 UEP-15/1200-D24 UEP-15/1200-D48 7.87(VO - 7.136) -63.4 15 - VO 56.16 VO - 15 -63.4 Accuracy of adjustment is subject to tolerances of resistor values and factoryadjusted output accuracy.

Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown limit (34V for "D48" models). Subsequent re-start will not occur until the input is brought back up to the Start-Up Threshold. This built in hysteresis prevents any unstable on/off situations from occurring at a single input voltage. Input voltages exceeding the input overvoltage shutdown specification listed in the Performance/Functional Specifications will cause the device to shutdown. A built-in hysteresis of 0.6 to 1.6 Volts for all models will not allow the converter to restart until the input voltage is sufficiently reduced. The two 6 Amp models do not feature overvoltage shutdown and withstand surges to 100V without shutting down. For custom overvoltage protection, contact DATEL. Input Reverse-Polarity Protection If the input-voltage polarity is accidentally reversed, an internal diode will become forward biased and likely draw excessive current from the power source. If the source is not current limited (<10A) nor the circuit appropriately fused, it could cause permanent damage to the converter. On/Off Control The input-side, remote On/Off Control function (pin 3) can be ordered to operate with either polarity (negative polarity available for 12 and 15 Volt models only). Positive-polarity devices (standard, no part-number suffix) are enabled when pin 3 is left open or is pulled high (+13V to VIN applied with respect to -Input, pin 2, (see Figure 2). Positive-polarity devices are disabled when pin 3 is pulled low (0-0.8V with respect to -Input). Negative-polarity devices are off when pin 3 is open or pulled high (+2.4V to +10V), and on when pin 3 is pulled low (0-0.5V). See Figure 3. 1 +INPUT 3 ON/OFF CONTROL 2 -INPUT Figure 3. Driving the Negative Polarity On/Off Control Pin Dynamic control of the remote on/off function is best accomplished with a mechanical relay or an open-collector/open-drain drive circuit (optically isolated if appropriate). The drive circuit should be able to sink appropriate current (see Performance Specs) when activated and withstand appropriate voltage when deactivated. Applying an external voltage to pin 3 when no input power is applied to the converter can cause permanent damage to the converter. Start-Up Time The VIN to VOUT start-up time is the interval of time where the input voltage crosses the turn-on threshold point, and the fully loaded output voltage enters and remains within its specified accuracy band. Actual measured times will vary with input source impedance, external input/output capacitance, and load. The UEP Series implements a soft start circuit that limits the duty cycle of the PWM controller at power up, thereby limiting the Input Inrush current. The On/Off Control to VOUT start-up time assumes the converter has its nominal input voltage applied but is turned off via the On/Off Control pin. The specification defines the interval between the time at which the converter is turned on and the fully loaded output voltage enters and remains within its specified accuracy band. Similar to the VIN to VOUT start-up, the On/Off Control to VOUT start-up time is also governed by the internal soft start circuitry and external load capacitance. Current Limiting When output increases to 120% to 190% of the rated output current, the DC/DC converter will go into a current limiting mode. In this condition the output voltage will decrease proportionately with increases in output current, thereby maintaining a somewhat constant power dissipation. This is commonly referred to as power limiting. Current limit inception is defined as the point where the full-power output voltage falls below the specified tolerance. See Performance/Functional Specifications. If the load current being drawn from the converter is significant enough, the unit will go into a short circuit condition. See "Short Circuit Condition." 1 +INPUT 200k 13V CIRCUIT 3 ON/OFF CONTROL 5V CIRCUIT 2 -INPUT Figure 2.

If the output voltage drops too low, the magnetically coupled primary side voltages will also drop, thereby shutting down the PWM controller. Following a time-out period, the PWM will restart, causing the output voltage to begin ramping to its appropriate value. If the short-circuit condition persists, another shutdown cycle will be initiated. This on/off cycling is referred to as "hiccup" mode. The hiccup cycling reduces the average output current, thereby preventing internal temperatures from rising to excessive levels. The UEP is capable of enduring an indefinite short circuit output condition. Thermal Shutdown These UEP converters are equipped with Thermal Shutdown Circuitry. If environmental conditions cause the internal temperature of the DC/DC converter rises above the designed operating temperature (typically 118C case), a precision temperature sensor will power down the unit. When the internal temperature decreases below the threshold of the temperature sensor the unit will self start. Output Overvoltage Protection Output voltages are monitored for an overvoltage condition via magnetic coupling to the primary side. If the output voltage should rise to a level which could be damaging to the load circuitry, the sensing circuitry will power down the PWM controller causing the output voltages to decrease. Following a time-out period the PWM will restart, causing the output voltages to ramp to their appropriate values. If the fault condition persists, and the output voltage again climbs to excessive levels, the overvoltage circuitry will initiate another shutdown cycle. This on/off cycling is referred to as "hiccup" mode.
