.fairchildsemi. FSDH0265RN, FSDM0265RN Green Mode Fairchild Power Switch (FPSTM) Features - Internal Avalanche Rugged Sense FET - Consumes only 0.65W at 240VAC & 0.3W load with Advanced Burst-Mode Operation - Frequency Modulation for EMI Reduction - Precision Fixed Operating Frequency - Internal Start-up Circuit - Pulse-by-Pulse Current Limiting - Abnormal Over Current Protection (AOCP) - Over Voltage Protection (OVP) - Over Load Protection (OLP) - Internal Thermal Shutdown Function (TSD) - Auto-Restart Mode - Under Voltage Lockout (UVLO) - Low Operating Current (3m A) - Adjustable Peak Current Limit - Built-in Soft Start Applications - SMPS for VCR, SVR, STB, DVD & DVCD Player - SMPS for Printer, Facsimile & Scanner - Adapter for Camcorder Related Application Notes - AN-4137, 4141, 4147(Flyback) / AN-4134(Forward) Description Each product in the FSDx0265RN (x for M, H) family consists of an integrated Pulse Width Modulator (PWM) and Sense FET, and is specifically designed for high performance off-line Switch Mode Power Supplies (SMPS) with minimal external ponents. Both devices are integrated high voltage power switching regulators which bine an avalanche rugged Sense FET with a current mode PWM control block. The integrated PWM controller Features include: a fixed oscillator with frequency modulation for reduced EMI, Under Voltage Lock Out (UVLO) protection, Leading Edge Blanking (LEB), an optimized gate turn-on/ turn-off driver, Thermal Shut Down (TSD) protection, Abnormal Over Current Protection (AOCP) and temperature pensated precision current sources for loop pensation and fault protection circuitry. When pared to a discrete MOSFET and controller or RCC switching converter solution, the FSDx0265RN devices reduce total ponent count, design size, weight while increasing efficiency, productivity and system reliability. Both devices provide a basic platform that is well suited for the design of cost-effective flyback converters. FPSTM is...
