FSGM0465RB

FSGM0465RB — Green-Mode Fairchild Power Switch (FPS™) March 2010 FSGM0465RB Green-Mode Fairchild Power Switch (FPS™) Features ƒ Soft Burst-Mode Operation for Low Standby Power Consumption and Low Noise Description The FSGM0465RB is an integrated Pulse Width Modulation (PWM) controller and SenseFET specifically designed for offline Switch-Mode Power Supplies (SMPS) with minimal external components. The PWM controller includes an integrated fixed-frequency oscillator, Under-Voltage Lockout (UVLO), LeadingEdge Blanking (LEB), optimized gate driver, internal soft-start, temperature-compensated precise current sources for loop compensation, and self-protection circuitry. Compared with a discrete MOSFET and PWM controller solution, the FSGM series can reduce total cost, component count, size, and weight; while simultaneously increasing efficiency, productivity, and system reliability. This device provides a basic platform suited for cost-effective design of a flyback converter. ƒ Precision Fixed Operating Frequency: 66kHz ƒ Pulse-by-Pulse Current Limit ƒ Various Protection Functions: Overload Protection (OLP), Over-Voltage Protection (OVP), Abnormal Over-Current Protection (AOCP), Internal Thermal Shutdown (TSD) with Hysteresis, Output-Short Protection (OSP), and Under-Voltage Lockout (UVLO) with Hysteresis ƒ Auto-Restart Mode ƒ Internal Startup Circuit ƒ Internal High-Voltage SenseFET: 650V ƒ Built-in Soft-Start: 15ms Applications ƒ Power Supply for LCD TV and Monitor, STB a...
