DESCRIPTION  
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™ 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  
WIDE VOLTAGE RANGE  
3
square inches), and high power density (22 watt/in ).  
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.  
The parts are packaged in hermetically sealed steel enclosures,  
making them ideal for use in military, aerospace, and high reliability  
industrial applications.  
DESIGN METHODOLOGY  
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.  
MILITARY TEMPERATURE RANGE  
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.  
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.  
INHIBIT FEATURE  
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.  
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
