FSL4110LR Datasheet | onsemi

Description The FSL4110LR is an integrated pulse width modulation (PWM) controller and 1000 V avalanche rugged Sense FET specifically designed for high input voltage offline Switching Mode Power Supplies (SMPS) with minimal external ponents. 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- pensated precise current sources for loop- pensation, and variable protection circuitry. pared with a discrete MOSFET and PWM controller solution, the FSL4110LR reduces total cost, ponent 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.
