FA1A50N
FA1A50N is Critical Conduction Mode PFC manufactured by Fuji Electric.
Overview
FA1A50 is power-factor correction converter IC operating in critical conduction mode. It realizes low power consumption by using high voltage CMOS process. It is equipped with many fault protection functions such as FB short-circuit detection circuit and double OVP function.
2. Features
- Very Low Standby Power by disusing Input Voltage Detection Resistors
- High-precision over current protection : 0.6V±2%
- Improved power efficiency at light load due to Maximum Frequency
Limitation
- Soften Audible Noise at Startup Over Shoot Reduction functions
- Low current consumption by CMOS process
- Start-up : 500µA(typ.), Operating : 1.5m A(typ.)
- Enabled to drive power MOSFET directly
- Output peak current, source : 500m A, sink : 1000m A
- Protects the output electrolytic capacitor by the double OVP function, even if a fault happen in the output detection.
- Short protection at feedback (FB) pin
- Under-voltage Lockout
- Restart timer
- 8-pin package (SOP)
