Overview
Bipolar IC FA7610CP(N)/12CP(N)/17CP(N)FA7610CP(N)/FA7612CP(N)/FA7617CP(N) For Switching Power Supply Control s Description 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 supply circuit.
