FA5550 / 51
1. Overview
FA5550/51 are control ICs for power factor correction converter with continuouse conduction mode (CCM) of
operation. Low power consumption is achieved by using high withstand voltage CMOS processes.
2. Features
・CCM PFC controller with few external components
・low power consumption by using high withstand voltage CMOS processes
・Built-in drive circuit for the power MOSFET,
Output current: 1A (source)/ 2A (sink)
・Over voltage protection function
・Brownout protection function
・Undervoltage Lockout function
FA5550: 9.6V ON/ 9V OFF; FA5551: 13.0V ON/9V OFF
・Open/short protection at feedback(FB) pin
・Operational frequency: 65kHz (typ)
・Packages: DIP-8/SOP-8
