FSFM260N / FSFM300N — Green-Mode Faric hild Power Switch (FPS™) www.DataShe et4U.com April 2009 FSFM260N / FSFM30 0N Green-Mode Fairchild Power Switch (F PS™) Features ! Internal Avalanche-Ru gged SenseFET ! Advanced Burst-Mode Ope ration Consumes Under Description The FSFM260/300 is an integrated Pulse Widt h Modulator (PWM) and SenseFET specific ally designed for high-performance offl ine Switch Mode Power Supplies (SMPS) w ith minimal external components. This d evice is an integrated high-voltage pow erswitching regulator that combines an avalanche-rugged SenseFET with a curren t-mode PWM control block. The PWM contr oller includes an integrated fi

xed-frequency oscillator, under-voltage lockout, leading-edge blanking (LEB), o ptimized gate driver, internal soft-sta rt, temperature-compensated precise-cur rent sources for a loop compensation, a nd self-protection circuitry. Compared with discrete MOSFET and PWM controller solutions, it can reduce total cost, c omponent count, size, and weight while simultaneously increasing efficiency, p roductivity, and system reliability.
