FSL126MR Datasheet PDF - Fairchild

●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 Limit

●Applications

●  SMPS for VCR, STB, DVD, & DVCD Players

●  SMPS for Home Appliance

●  Adapter
