DESCRIPTION
Interpoint’s MHV Series™ 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 converters will withstand transients of up to 80 V for up to 120
milliseconds while maintaining output voltages (with the exception of
the 12 volt single and dual outputs which will withstand transients up
to 75 volts and the 15 volt single and dual outputs which will withstand up to 60 volts). The MHV Series operates at a full 15 watts of
output power (10 watts for the 3.3 volt single output) over the military temperature range of –55°C to +125°C while maintaining low
input and output noise.
CONVERTER DESIGN
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
internal converters with one converter phase shifted 180° from the
other to create a dual phase/phase-shifted operation. Each of the
internal converters operates at approximately one-half of the clock
frequency. This proprietary technology eliminates cross regulation,
minimizes input ripple, greatly reduces output ripple and improves
efficiency. On the triple output models, this design provides
completely independent regulation with no cross regulation effect
between the main and auxiliary outputs and no minimum loading
required on the main output.
INHIBIT FUNCTION
Open collector TTL levels control the inhibit circuit. The converter is
enabled when the inhibit terminal is left unconnected or when the
inhibit terminal is connected to a voltage between 11.5 and 50 V.

When a low (0.8 V) is applied to the inhibit terminal the converter
shuts down, typically drawing 8.4 mA of input current. Inhibit
terminal resistance is 3.3 k ohms and draws 8.4 mA, typical.
SYNCHRONIZATION FUNCTION
Applying an external signal of 40% to 60% duty cycle and 500 to
700 kHz will synchronize the converter to your system requirements.
Free run clock frequency is approximately 600 kHz. If not used, the
sync terminal must be left unconnected.
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 6 and trim
tables for more information.
UNDERVOLTAGE LOCKOUT
An undervoltage lockout of approximately 7 VDC keeps system
current levels low during startup.
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.

Notes
1. Guaranteed by design, not tested.
2. The sum of the 12 volt auxiliary output currents may not exceed 416 mA.
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.
4. 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:

mV
ms

mS
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.
5. Load fault is a short circuit (<50 mΩ). Recovery is into a resistive load.
6. Load step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
7. Input step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
