The FSL126HR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for high performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL126HR includes integrated high-voltage power switching regulators that combine an avalanche-rugged SenseFET with a current-mode PWM control block.
Features
■ Internal Avalanche-Rugged SenseFET (650V)
■ Under 50mW Standby Power Consumption at 265VAC, No-load Condition with Burst Mode
■ Precision Fixed Operating Frequency with Frequency Modulation for Attenuating EMI
