FSL206MR is a green mode Fairchild Power Switch (FPS) with an integrated Pulse-Width Modulator (PWM) and SenseFET from Fairchild Semiconductor Corporation. The product has a fixed operating frequency, low power consumption, no need for auxiliary bias winding, frequency modulation to reduce EMI, line under-voltage protection (LUVP), pulse current limiting, low under-voltage lockout (UVLO), ultra-low operating current, built-in soft-start and startup circuit, various protections (overload protection (OLP), overvoltage protection (OVP), thermal shutdown (TSD), abnormal overcurrent protection (AOCP)) and automatic restart mode.
The FSL206MR is an integrated Pulse-Width Modulator (PWM) and SenseFET specifically designed for high-performance offline Switched-Mode Power Supplies (SMPS) with minimal external components. It combines an avalanche-rugged SenseFET with a Current-Mode PWM control block to regulate high-voltage power.
It consumes less than 25mW at no-load when using a bias winding.
