1000 V SenseFET Integrated Power Switch
FSL4110LR
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 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.
