FSL126HR Datasheet Green Mode Fairchild Power Switch

Manufacturer: Fairchild (now onsemi)

Overview: FSL126HR — Green Mode Fairchild Power Switch (FPS™) March 20111 FSL126HR Green Mode Fairchild Power Switch.

General Description

The FSL126HR integrated Pulse Width Modulator (PWM) and SenseFET is specifically designed for highperformance 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.

The integrated PWM controller includes: Under-Voltage Lockout (UVLO) protection, Leading-Edge Blanking (LEB), a frequency generator for EMI attenuation, an optimized gate turn-on/turn-off driver, Thermal Shutdown (TSD) protection, and temperaturecompensated precision current sources for loop compensation and fault protection circuitry.

Key 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: 20ms 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 S.
