FSFM260N / FSFM261N / FSFM300N Green-Mode Farichild Power Switch (FPS) FSFM260N / FSFM261N / FSFM300N Green-Mode ON Semiconductor Power Switch Features Description Internal Avalanche-Rugged SenseFET The FSFM260/261/300 is an integrated Pulse Width Modulator (PWM) and SenseFET specifically designed Advanced Burst-Mode Operation Consumes Under for high-performance offline Switch Mode Power 1W at 240V and 0.5W Load AC Supplies (SMPS) with minimal external components. Precision Fixed Operating Frequency: 67kHz This device is an integrated high-voltage power- Internal Startup Circuit switching regulator that combines an avalanche-rugged Over-Voltage Protection (OVP) SenseFET with a current-mode PWM control block. The Overload Protection (OLP) PWM controller includes an integrated fixed-frequency Internal Thermal Shutdown Function (TSD) oscillator, under-voltage lockout, leading-edge blanking Abnormal Over-Current Protection (AOCP) (LEB), optimized gate driver, internal soft-start, Auto-Restart Mode temperature-compensated precise-current sources for a loop compensation, and self-protection circuitry. Under-Voltage Lockout (UVLO) with Hysteresis Compared with discrete MOSFET and PWM controller Low Operating Current: 2.5mA solutions, it can reduce total cost, component count, size, Built-in Soft-Start: 15ms and weight while simultaneously increasing efficiency, productivity, and system reliability. This device is a basic platform for cost-effective designs of flyback converters. Applications Power Supply for LCD TV and Monitor, VCR, SVR, STB, DVD, and DVD Recorder Adapter 2009 Semiconductor Components Industries, LLC.
