FSDM0465R

www.DataSheet4U.com June 2006 FSCM0465R Green Mode Fairchild Power Switch (FPS™) FSCM0465R Green Mode Fairchild Power Switch (FPS™) Features „ Internal Avalanche Rugged SenseFET „ Low Start-up Current (max. 40µA) „ Low Power Consumption; under 1W at 240VAC and Description The FSCM0465R 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. Compared with a discrete MOSFET and PWM controller solution, it can reduce total cost, component count, size, and weight while simultaneously increasing efficiency, productivity, and system reliability. This device is a basic platform well suited for cost-effective designs of flyback converters. 0.4W Load „ Precise Fixed Operating Frequency (66kHz) „ Frequency Modulation for Low EMI „ Pulse-by-Pulse Current Limiting (Adjustable) „ Over-Voltage Protection (OVP) „ Overload Protection (OLP) „ Thermal Shutdown Function (TSD) „ Auto-Restart Mode „ Under-Voltage Lock Out (UVLO) with Hysteresis „ Built-in Soft-St...
