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 power-
supply circuit, the FA7612CP(N) for a step-down power-supply
circuit and FA7617CP(N) for a flyback power supply circuit.
