FSL126HR is a green mode Fairchild Power Switch (FPS™) with internal avalanche-rugged SenseFET (650V) and low standby power consumption. It also features precision fixed operating frequency, internal startup circuit, built-in soft-start, pulse-by-pulse current limiting, and various protections.
The document describes the FSL126HR integrated Pulse Width Modulator (PWM) and SenseFET designed for high-performance offline Switch-Mode Power Supplies. It combines an avalanche-rugged SenseFET with a current-mode PWM control block to reduce component count and increase efficiency in flyback converters.
