DESCRIPTION  
Interpoint’s MTO Series™ of DC/DC converters delivers 15 watts of  
output power with three output voltages and a choice of two input  
voltage ranges. The MTO Series converters are packaged in  
hermetically sealed metal cases and operate at full load over a case  
temperature range of -55°C to +85°C (measured at the base plate  
of the converter).  
FEATURES  
An inhibit terminal, pin 8, provides shut-down and start-up control.  
Applying a logic low (<0.8 V) will disable the output of the converter  
reducing input current to 8 mA, typical. Leaving the terminal uncon-  
nected or connecting it to Vin will enable the converter. The inhibit  
pin has an open circuit voltage of approximately 10 volts.  
CONVERTER DESIGN  
Soft-start provides a controlled 20 milliseconds turn-on to minimize  
inrush current and reduce overshoot at initial start-up or when inhibit  
is released.  
The push-pull forward topology coupled with pulse-width modulation  
minimizes output noise and maintains good regulation. Nominal  
switching frequency is 250 kHz. Although an internal input filter  
reduces input ripple current, for applications requiring conformance  
to MIL-STD-461C, CE03, use the MTO in conjunction with  
Interpoint’s FM-461 EMI filter.  
Internal current limiting circuitry protects all three outputs against  
short circuits. When output power exceeds approximately 125% of  
maximum output power, the output currents are limited. In addition,  
separate current limiting circuitry protects each output individually.  
Operating at maximum ratings may require removing self-generated  
heat. To increase heat dissipation, heat conducting material can be  
used in contact with the converter’s base plate. Interpoint’s Thermal  
Mounting Pad (TMP), model TMP-002, is designed for use with the  
MTO converter.  
PACKAGING  
MTO converters are packaged in hermetically sealed metal cases.  
The cases are constructed of cold-rolled steel with a fused tin finish.  
MTO converters can be purchased in a flanged or non-flanged case.  
The flanged option provides increased heat dissipation and also  
provides greater stability when mechanically secured.
