5
ONA
Channel A Master ON/OFF Output Control. Drive ONA logic high to enable channel A +3.3V, +5V, and
±12V outputs. V+12VIN must be > UVLO threshold.
6
ONB
Channel B Master ON/OFF Output Control. Drive ONB logic high to enable channel B +3.3V, +5V, and
±12V outputs. V+12VIN must be > UVLO threshold.
7
GND Ground
8
PGOODA
Channel A Power-Good Output. PGOODA is an open-drain output that pulls low when a fault is detected on
channel A outputs.
9
PGOODB
Channel B Power-Good Output. PGOODB is an open-drain output that pulls low when a fault is detected on
channel B outputs.
