FSL4110LR

1000V Integrated Power Switch with Line OVP and no bias winding for 9Watt offline flyback converters

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 fixed-frequency oscillator, Under-Voltage Lockout (UVLO), Leading-Edge Blanking (LEB), optimized gate driver, soft-start, temperature-compensatedprecise 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.

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-Voltage Lockout (UVLO) and Line Over-Voltage Protection (LOVP) with Hysteresis.
  • Built-in Internal Startup and Soft-Start Circuit
  • Fixed 1.6 s Restart Time for Safe Auto-Restart Mode of All Protections
