FA5590N, FA5591N - Power Supply Control IC
Description
FA5590/FA5591 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 which stops the operation when abnormal output voltage is detected.
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
