description
Interpoint's MHV SeriesTM of DC/DC converters offers a wide input voltage range of 16 to 50 VDC and a choice of nine different output voltage configurations comprised of single, dual or triple outputs. The 3.3 volt single, 5 volt single and dual and the triple output models will withstand transients of up to 80 volts for up to 120 milliseconds while maintaining output voltages. The 12 volt single and dual outputs will withstand transients up to 75 volts and the 15 volt single and dual outputs will withstand up to 60 volts for 120 milliseconds. The MHV Series operates at 15 watts of output power (10 watts for the 3.3 volt single output) over the military temperature range of -55C to +125C while maintaining low input and output noise.
inhibit FunCtion
The converter is enabled when the inhibit terminal is left unconnected. When the inhibit terminal is pulled low (<0.8 V) the converter shuts down, typically drawing 8.4 mA at 28 Vin or 15 mA at 50 Vin. Sinking current required is Vin / 3.3 K ohm.
synChronization FunCtion
Converter Design
Applying an external signal of 40% to 60% duty cycle and 490 to 710 kHz for singles and duals output models will synchronize the converter to your system requirements. For triple output models the external frequency range is 500 to 700 kHz. Free run clock frequency is approximately 600 kHz. If not used, the sync terminal must be left unconnected.
MHV Series DC/DC converters are switching regulators that use continuous flyback conversion topology with a clock frequency of approximately 600 kHz. MHV Series converters incorporate two pulse width modulators (PWM) with one PWM phase shifted 180 from the other to create a dual phase/phase-shifted operation. Each of the PWMs operates at approximately one-half (300 kHz) of the clock frequency. This proprietary technology minimizes input ripple and improves efficiency. On singles the output ripple is reduced. Cross regulation is eliminated on dual output models which are independently regulated and do not require load balancing or minimum loading. On triple output models, this design provides completely independent regulation with no cross regulation effect between the main and auxiliary outputs and no minimum loading is required on the main output.
trim
Single output converters feature a trim range of as low as 80% to as high as 110% of Vout nominal, depending on the model. To trim up, connect a resistor from output common (pin 4) to the trim terminal (pin 3). To trim down, connect a resistor from the positive output (pin 5) to the trim terminal (pin 3). See Figure 4 and trim tables for more information.
sCreening
The converters are offered with standard screening, "ES" screening, or fully compliant to "883" MIL-PRF-38534 Class H screening. Standard microcircuit drawings (SMD) are available.

unDervoltage loCkout output voltage options
An undervoltage lockout of approximately 7 VDC keeps system current levels low during startup. Low line dropout typically occurs at approximately 12 Vin to 17 Vin depending on model. See Figures 12, 16 and 17.
The MHV Series converters are capable of providing other output voltage options in addition to those characterized on this datasheet. Contact your sales representative to discuss other output voltage options, www.interpoint.com/contacts.
short CirCuit proteCtion
Under short circuit conditions of 130% or more of full load current, the converter will protect itself by shutting down. Short circuit duration should be brief because power dissipation may cause internal temperatures to rise rapidly. Restart is automatic upon removal of the short circuit.

Interpoint converters may use one or more of the following US patents 5,521,807, 5,694,303, and 5,631,822.

Notes for Triple Output Models 1. guaranteed by design, not tested. 2. The sum of the 12 volt auxiliary output currents may not exceed 416 mA. 3. The sum of the auxiliary output power may not exceed 5 watts. Up to 80% of the total power (5W) is available from either auxiliary providing the opposite auxiliary is carrying 20% of the total auxiliary power used. 4. Load regulation for the +5 is specified at 0.0 to 2.0 A with the aux. both held at 2.5 W (208 mA). Load regulation for the auxiliary. is specified as both auxiliaries from 0.0 to 2.5 W (208 mA) at the same time with the +5 held at 2.0 A.
5. Cross regulation occurs between the two auxiliaries and is measured on -aux. +5 is held constant at 2.0 A. Cross regulation is specified for two conditions: A. Positive aux. = 2.5 W (50%); negative aux. = 2.5 W to 0.5 W (50% to 10%). B. From +Po = 70% and -Po = 30% to + Po = 30% and -Po =70%. Above conditions are referenced to 50%/50% balanced loads. 6.Loadfaultisashortcircuit(<50m).Recoveryisintoaresistiveload. 7.Step load transition 10 s. Recovery = time to settle to within 1% of VOUT final value. 8.Step line transition 10 s. Recovery = time to settle to within 1% of VOUT final value.

Notes for Triple Output Models 1. guaranteed by design, not tested. 2. The sum of the 15 volt auxiliary output currents may not exceed 333 mA. 3. The sum of the auxiliary output power may not exceed 5 watts. Up to 80% of the total power (5W) is available from either auxiliary providing the opposite auxiliary is carrying 20% of the total auxiliary power used. 4. Load regulation for the +5 is specified at 0.0 to 2.0 A with the aux. both held at 2.5 W (167 mA). Load regulation for the auxiliary. is specified as both auxiliaries from 0.0 to 2.5 W (167 mA) at the same time with the +5 held at 2.0 A.
5. Cross regulation occurs between the two auxiliaries and is measured on -aux. +5 is held constant at 2.0 A. Cross regulation is specified for two conditions: A. Positive aux. = 2.5 W (50%); negative aux. = 2.5 W to 0.5 W (50% to 10%). B. From +Po = 70% and -Po = 30% to + Po = 30% and -Po =70%. Above conditions are referenced to 50%/50% balanced loads. 6.Loadfaultisashortcircuit(<50m).Recoveryisintoaresistiveload. 7.Steploadtransition10s.Recovery=timetosettletowithin1%of VOUT final value. 8.Step line transition 10 s.
