Bipolar IC

For Switching Power Supply Control

FA7610CP(N)/12CP(N)/17CP(N)

FA7610CP(N)/FA7612CP(N)/FA7617CP(N)

■ Description

■ Dimensions, mm

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.
