FSFM261N Datasheet Green-mode Fairchild Power Switch

Manufacturer: Fairchild (now onsemi)

Overview: FSFM260N / FSFM261N / FSFM300N — Green-Mode Farichild Power Switch (FPS™) August 2009 FSFM260N / FSFM261N / FSFM300N Green-Mode Fairchild Power Switch.

General Description

The FSFM260/261/300 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, leading-edge blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise-current sources for a loop compensation, and self-protection circuitry.
