3 PROG input Power-limit setting input, 0.4 V to 4 V recommended operating range, 2 mA sink current maximum
4 TIMER bidirectional Fault timing capacitor input/output connection
5 GND power_in Ground
6 PG tri_state Power good reporting open-drain output, 10 mA sink current maximum
7 OUT input Output voltage feedback input, 0 V to 80 V recommended operating range
8 GATE output Gate output for driving external N-channel MOSFET
9 SENSE input Current-limit sense input
10 VCC power_in Supply input voltage, 9 V to 80 V operating range
