Description
FSES0765RG is a Fairchild Power Switch (FPS) specially
designed for off-line SMPS of CRT monitors with minimal
external components. This device combines a current mode
PWM controller with a high voltage power SenseFET in a single
www.DaptaaSchkeageet4.U.Tcohme PWM controller features an integrated
oscillator to be synchronized with the external sync signal,
under voltage lockout, optimized gate driver and
temperature-compensated precise current sources for the loop
compensation. This device also includes various fault
protection circuits such as over voltage protection, over load
protection, abnormal over current protection and over
temperature protection. Compared with discrete MOSFET and
PWM controller solutions, FPS can reduce total cost,
component count, size and weight while simultaneously
increasing efficiency, productivity and system reliability. This
device is well suited for cost effective CRT-monitor power
supplies.
