DESCRIPTION
Seriesof DC/DC converters offers watts output power over full military temperature range with efficiency. Thick-film hybrid techniques provide military/aerospace reliability levels optimum miniaturization. Series power density rating watts/in3. converters packaged hermetically sealed metal cases, making them ideal military, aerospace other high reliability applications. Units available with standard screening, "ES" screening, fully compliant versions (see Section screening conditions).
SYNCHRONIZATION
offers synchronization feature that allows designer match switching frequency converter frequency system clock. free-run (unsynchronized) mode, unit switches (nominal). sync mode, converter will frequency between kHz. sync control operates with quasi-TTL signal duty cycle between 60%. Synchronizing converter with system clock allows designer confine switching noise clock transitions, minimizing interference reducing need filtering. sync should connected input common when use.
CONVERTER DESIGN
converters constant frequency, pulse-width modulated switching regulators which quasi-square wave, single ended, forward converter design. Tight load regulation typical) maintained wide bandwidth magnetic feedback and, single output models, through remote sense. dual output models, positive output independently regulated negative output cross regulated through tightly coupled magnetics shunt regulators. Indefinite short circuit protection overload protection provided constant current-limit feature. This protective system senses current converter's secondary stage limits approximately 115% maximum rated output current. converters provided with internal filtering capacitors that help reduce need external components normal operation. systems that require compliance with MIL-STD-461C's CE03 standard, Interpoint offers filter/transient suppression modules (including FMC-461, FMD-461 FM-704A series filters) which will result compliance. Contact your Interpoint representative further details.
WIDE VOLTAGE RANGE
converters designed provide full power operation over full voltage range. Operation below volts, including MIL-STD-704E emergency power conditions possible with derated power. Refer line dropout graph (Figure details.
IMPROVED DYNAMIC RESPONSE
feed-forward compensation system provides excellent dynamic response noise rejection. Audio rejection typically min. maximum step line transient response typically less than
INHIBIT FUNCTION
converters provide inhibit terminal that used disable internal switching, resulting output very quiescent input current. converter inhibited when compatible (0.8 applied inhibit pin. unit enabled when pin, which internally connected pull-up resistor, left unconnected connected open-collector gate. open circuit output voltage associated with inhibit inhibit mode, maximum must sunk from inhibit pin.
