DESCRIPTION
The MHF Series™ of DC/DC converters offer up to 12 watts of
power from single or dual outputs in a single package over a the full
military temperature range. Thick film hybrid manufacturing tech-
nology produces high levels of miniaturization, giving the MHF
Series converters a low profile (0.330 inch), small board area (1.65
square inches), and high power density (22 watt/in

).
The parts are packaged in hermetically sealed steel enclosures,
making them ideal for use in military, aerospace, and high reliability
industrial applications.
elements on both the input and output to help reduce the need for
external components. For information about filtering to meet MIL-
STD-461’s CE03 test, contact your Interpoint representative.

The MHF Series is designed to provide full power operation over the
input voltage range of 16 to 40 volts. The 15 volt models provide a
19 to 40 volt range. Operation below 16 volts (or 19 volts for the 15
volt models), including operation in MIL-STD-704E emergency
power conditions, is possible with derated output power. Please
refer to the low line drop-out graphs, Figures 9 and 10.

ETHODOLOGY
The MHF converters are switching regulators which use a quasi-
square wave, single ended forward converter design with a nominal
switching frequency of 600 kHz. Isolation between input and output
circuits is provided with a transformer in the forward power loop and
a temperature insensitive optical link in the feedback control loop.
Output regulation is accomplished with constant frequency pulse
width modulation. Both line and load regulation are typically within
10 mV.
On dual output models, the positive output is independently regu-
lated and the negative output is cross-regulated. Figures 7 and 8
illustrate what effects load changes have on the negative output.
Indefinite short circuit protection and overload protection are
provided by sensing output load current and restricting the output
current to approximately 125% of full load output current. Since the
output current is sensed in the secondary stage, the result is a
predictable, constant output current control with no foldback char-
acteristics. MHF converters are provided with internal filtering

The MHF Series provides full power operation at case temperatures
from –55°C up to +125°C. All 12 and 15 volt models in both single
and dual output configurations provide full power operation at
+125°C with derated power to 135°C. The +5 volt model provides
full power at 110°C derated to 0% at 130°C. Depending on operating
levels, air flow, and ambient temperature; heat sinking may be
required.

EATURE
An inhibit terminal is provided that can be used to disable internal
switching, resulting in a very low quiescent input current. An open
collector TTL compatible low (≤0.8V) is required to control the inhibit
function. This level may be supplied by an open collector gate since
the inhibit pin is provided with an internal pull-up resistor.
