IB_S-2W Series 2W, FIXED INPUT, ISOLATED & REGULATED SINGLE OUTPUT DC-DC CONVERTER multi-country patent protection FEATURES Small Footprint SIP Package 1KVDC Isolation Temperature Range: -40C to +85C No External Component Required Internal SMD construction Continuous Short Circuit Protection Industry Standard Pinout RoHS Compliance RoHS PRODUCT PROGRAM Input Part Number IB0505S-2W IB1205S-2W IB1505S-2W* IB2405S-2W Voltage (VDC) Nominal 5 12 15 24 Range 4.75-5.25 11.40-12.60 14.25-15.75 22.8-25.2 Voltage (VDC) 5 5 5 5 Output Current (mA) Max 400 400 400 400 Min 40 40 40 40 Switching Efficiency frequency (%, Typ) (KHz) 70 71 71 71 333 58 66 APPLICATIONS The IB_S-2W Series are specially designed for applications where a single power supply is highly isolated from the input power supply in a distributed power supply system on a circuit board. These products apply to: 1) Where the voltage of the input power supply is fixed (voltage variation 5%); 2) Where isolation is necessary between input and output (isolation voltage 1000VDC); 3) Where the regulation of the output voltage and the output ripple and noise are demanded. * Designing.

See detailed operation instructions at Testing of Power Converter section, application notes. Note: 1. All specifications measured at TA=25C, humidity<75%, nominal input voltage and rated output load unless otherwise specified. 2. See below recommended circuits for more details.

L L Vin Cin +Vo DC DC (Figure 1) Cout GND 0V It should also be noted that the inductance and the frequency of the "LC" filtering network should be staggered with the DC/DC frequency to avoid mutual interference. However, the capacitance of the output filter capacitor must be TYPICAL TEMPERATURE CURVE proper. If the capacitance is too big, a startup problem might arise. For every channel of output, provided the safe and reliable operation is ensured, the greatest capacitance of its filter capacitor sees (Table 1).

First Angle Projection (0.276) (Bottom View) RECOMMENDED FOOTPRINT Top view,grid:2.54mm(0.1inch), diameter:1.00mm(0.039inch) Overload Protection Under normal operating output circuit of these conditions, has the no products (0.079) 5.08 (0.200) protection against over-current. The simplest method is to connect a self-recovery fuse in series at the input end or add a circuit breaker to the circuit.

If the actual output power is very small, please connect a resistor with proper resistance at the output end in parallel to increase the load, or use our company's products with a lower rated output power. When the environment temperature is higher than 71C, the product output power should be less then 60% of the rated power. No parallel connection or plug and play.
