Applications
Down Hole Exploration Tools current limit point exhibits slightly negative temperature coefficient reduce possibility thermal runaway. external Inhibit port provided control converter operation. converter's operation inhibited when this pulled low. designed driven open collector logic device. left open normal operation nominal open circuit voltage 4.0V with respect Input Return (pin output voltage models adjusted using single external resistor.
Circuit series converters utilize single-ended forward topology with resonant reset. nominal switching frequency 500KHz. Electrical isolation tight output regulation achieved through magnetically coupled feedback. Voltage feed-forward with duty factor limiting provides high line rejection protection against output over voltage event internal control loop failure. This mechanism limits maximum output voltage approximately over nominal regardless line voltage. Output current limited under load fault condition approximately 125% rated load maximum operating case temperature. overload condition causes converter output behave like constant current source with output voltage dropping below nominal. converter will resume normal operation when load current reduced below current limit point. This protects converter from both overload short circuit conditions.

HTA-SERIES Technical Notes:
Remote Sensing
This feature available only single output models. Connection Sense Sense leads remotely located load permits compensation resistive voltage drop between converter output load when they physically separated significant distance. This connection allows regulation placard voltage point application. When remote sensing features used, sense leads should connected their respective output terminals converter. combination compensation voltage drop output voltage adjustment (described below `Output Voltage Adjustment' section) limited nominal output voltage.
