Product overview
Overview
Description
The FSL126MR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for high performance offline Switch-Mode Power Supplies (SMPS) with minimal external components. FSL126MR 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 Internal Startup Circuit Built-in Soft-Start: 15ms Pulse-by-Pulse Current Limiting Various Protections: Over-Voltage Protection (OVP), Overload Protection (OLP), Output-Short Protection (OSP), Abnormal Over-Current Protection (AOCP), Internal
Thermal Shutdown Function with Hysteresis (TSD) Auto-Restart Mode Under-Voltage Lockout (UVLO) Low Operating Current: 1.8mA Adjustable Peak Current LimitApplications SMPS for VCR, STB, DVD, & DVCD Players SMPS for Home Appliance Adapter
