FA5695
1. Description
FA5695 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±5%
 Improved power efficiency at light load due to Maximum Frequency Limitation
 No Audible Noise at Startup
Soft-Startup and Soft-OVP functions
 Low current consumption by CMOS process
Start-up : 80µA(max.), Operating : 2mA(typ.)
 Enabled to drive power MOSFET directly
Output peak current, source : 1000mA, sink : 1000mA
 Protects the output electrolytic capacitor by the double OVP function, even if a fault happen in the output detection.
 Open/short protection at feedback (FB) pin
 Under-voltage Lockout: 13V ON / 9V OFF
 Restart timer
 Standby function
 8-pin package (SOP)
