Description
The FSFM260/300 is an integrated Pulse Width Modulator (PWM) and SenseFET specifically designed for high-performance offline Switch Mode Power Supplies (SMPS) with minimal external components.
This device is an integrated high-
voltage powerswitching regulator that combines an avalanche-rugged SenseFET with a current-mode PWM control block.
The PWM controller includes an integrated fixed-frequency oscillator, under-
voltage lockout, l...
