FA7612CPN - Fuji Electric

FA7612CPN Bipolar IC

The FA7610CP(N), 7612CP(N) and 7617CP(N) are bipolar ICs containing basic circuits necessary for PWM-type switching power supply control. To minimize the number of external discrete components, the FA7610CP(N) is provided for a flyback or step-up powersupply circuit, the FA7612CP(N) for a step-down power-supply circuit and FA7617CP(N) for a flyback power sup.

Features

FA7610CP(N)
