FA7617CP(N)

• For flyback transformer-type power-supply circuit (maximum output duty = 67% typical)
• Open collector output
• PWM-type switching power supply control
• Low-voltage operation (VCC = 3.6 to 22V)
• Latch-mode short-circuit protection function (no malfunction by noise)
• Soft-start function
• Undervoltage lockout function
• One capacitor shared for short circuit protection and for softstart to minimize the number of external discrete components

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.
