Pin No Pin Name 1 GND 2 FB 3 BO/OVP Function − Feedback pin Adjust the BO level Latch input 4 CS Current sense + OPP adjustment Latch input 5 Vcc 6 DRV Supplies the controller – protects the IC Driver output Pin Description The controller ground. Hooking an optocoupler collector to this pin will allow regulation. A voltage below the progra.
such as a timer−based auto−recovery short circuit protection, lossless OPP, and an easily adjustable Brown Out (BO) pin. Two inputs are provided to latch off the part in a practical way, for instance with OVP and OTP events. Several options exists to chose latch or auto−recovery for these events.
