Product Overview

The FSL4110LRN is a 1000V SenseFET Integrated Power Switch 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 fixed frequency 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. Compared with a discrete MOSFET and PWM controller solution, the FSL4110LR reduces total cost, component count, PCB size and weight; while simultaneously increasing efficiency, productivity and system reliability. This device provides a basic platform for cost-effective design of a flyback converter.
  • Built-in avalanche rugged 1000V SenseFET
  • 50kHz Precise fixed operating frequency
  • 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
  • Built-in internal startup and soft-start circuit
  • Fixed 1.6s Restart time for safe auto-restart mode of all protections
  • Overload protection (OLP)
  • Over-voltage protection (OVP)
  • Abnormal over-current protection (AOCP)
  • Internal thermal shutdown (TSD) with hysteresis
  • Under-voltage lockout (UVLO) and line over-voltage protection (LOVP) with hysteresis
