FA7617CPN Overview
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 ponents, 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. s Dimensions, mm SOP-8 8 5.
FA7617CPN Key Features
- For flyback transformer-type or step-up power-supply circuit (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 softstart to minimize the number of external discrete ponents
- For step-down power-supply circuit (maximum output duty = up to 100%)
- Open collector output
FA7617CPN Applications
- Battery power supply for portable equipment
