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.

s Features

FA7610CP(N)

(maximum output duty = 64% typical)

• Totem-pole predriver

• 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 soft-

start to minimize the number of external discrete components

FA7612CP(N)

• For step-down power-supply circuit

(maximum output duty = up to 100%)

• 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 soft-

start to minimize the number of external discrete components

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 soft-

start to minimize the number of external discrete components

s Applications

• Battery power supply for portable equipment
