DESCRIPTION  
SYNCHRONIZATION  
The MHD offers a synchronization feature that allows the designer  
to match the switching frequency of the converter to the frequency  
of the system clock. In free-run (unsynchronized) mode, the MHD  
unit switches at 625 kHz (nominal). In sync mode, the converter will  
run at any frequency between 500 kHz and 675 kHz. The sync  
control operates with a quasi-TTL signal at any duty cycle between  
40% and 60%.  
The MHD Series™ of DC/DC converters offers up to 20 watts of  
output power over the full military temperature range with up to 84%  
efficiency. Thick-film hybrid techniques provide military/aerospace  
reliability levels and optimum miniaturization. The MHD Series  
3
power density rating is up to 21 watts/in .  
MHD converters are packaged in hermetically sealed metal cases,  
making them ideal for use in military, aerospace and other high reli-  
ability applications. Units are available with standard screening,  
“ES” screening, or fully compliant SMD versions (see Section C2 for  
screening conditions).  
Synchronizing the converter with the system clock allows the  
designer to confine switching noise to clock transitions, minimizing  
interference and reducing the need for filtering. The sync pin should  
be connected to input common pin when not in use.  
CONVERTER DESIGN  
WIDE VOLTAGE RANGE  
The MHD converters are constant frequency, pulse-width mod-  
ulated switching regulators which use a quasi-square wave, single  
ended, forward converter design. Tight load regulation (5 mV  
typical) is maintained via wide bandwidth magnetic feedback and,  
on single output models, through use of remote sense. On dual  
output models, the positive output is independently regulated and  
the negative output is cross regulated through the use of tightly  
coupled magnetics and shunt regulators.  
The MHD converters are designed to provide full power operation  
over a full 16 to 40 VDC voltage range. Operation below 16 volts,  
including MIL-STD-704E emergency power conditions is possible  
with derated power. Refer to the low line dropout graph (Figure 15)  
for details.  
IMPROVED DYNAMIC RESPONSE  
The MHD feed-forward compensation system provides excellent  
dynamic response and noise rejection. Audio rejection is typically 50  
dB. The min. to maximum step line transient response is typically  
less than 4%.  
Indefinite short circuit protection and overload protection are  
provided by a constant current-limit feature. This protective system  
senses current in the converter’s secondary stage and limits it to  
approximately 115% of the maximum rated output current.  
INHIBIT FUNCTION  
MHD converters provide an inhibit terminal that can be used to  
disable internal switching, resulting in no output and very low  
quiescent input current. The converter is inhibited when a TTL  
compatible low (0.8 V) is applied to the inhibit pin. The unit is  
enabled when the pin, which is internally connected to a pull-up  
resistor, is left unconnected or is connected to an open-collector  
gate. The open circuit output voltage associated with the inhibit pin  
is 9 to 11 V. In the inhibit mode, a maximum of 8 mA must be sunk  
from the inhibit pin.  
MHD converters are provided with internal filtering capacitors that  
help reduce the need for external components in normal operation.  
For systems that require compliance with MIL-STD-461C’s CE03  
standard, Interpoint offers filter/transient suppression modules  
(including the FMC-461, FMD-461 and FM-704A series filters) which  
will result in compliance. Contact your Interpoint representative for  
further details.
