FSL4110LR Datasheet 1000v Sensefet Integrated Power Switch

Manufacturer: Fairchild (now onsemi)

Overview: FSL4110LR — 1000 V SenseFET Integrated Power Switch December 2015 FSL4110LR 1000 V SenseFET Integrated Power.

General Description

The FSL4110LR is an integrated pulse width modulation (PWM) controller and 1000 V avalanche rugged SenseFET specifically designed for high input voltage offline Switching Mode Power Supplies (SMPS) with minimal external components.

VCC can be supplied through integrated high-voltage power regulator without auxiliary bias winding.

The integrated PWM controller includes a fixedfrequency oscillator, Under-Voltage Lockout (UVLO), Leading-Edge Blanking (LEB), optimized gate driver, soft-start, temperature-compensated precise current sources for loop-compensation, and variable protection circuitry.

Key Features

  • Built-in Avalanche Rugged 1000 V SenseFET.
  • Precise Fixed Operating Frequency: 50 kHz.
  • VCC can be supplied from either bias-winding or self- biasing.
  • Soft Burst-Mode Operation Minimizing Audible Noise.
  • Random Frequency Fluctuation for Low EMI.
  • Pulse-by-Pulse Current Limit.
  • Various Protection Functions: Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD) with Hysteresis. Under-Voltag.
