FSDM07652REWDTU Datasheet

Controllore PWM in modalità corrente


The FSDM0465RE, FSDM0565RE and FSDM07652REWDTU are an integrated Pulse Width Modulator (PWM) andSenseFET specifically designed for high-performanceoffline Switch Mode Power Supplies (SMPS) withminimal external components. This device is anintegrated high-voltage power-switching regulator thatcombines an avalanche-rugged SenseFET with acurrent mode PWM control block. The PWM controllerincludes an integrated fixed-frequency oscillator, undervoltagelockout, leading-edge blanking (LEB), optimizedgate driver, internal soft-start, temperature-compensatedprecise-current sources for a loop compensation, andself-protection circuitry. Compared with a discreteMOSFET and PWM controller solution, it can reduce totalcost; component count, size, and weight; whilesimultaneously increasing efficiency, productivity, andsystem reliability. This device is a basic platform wellsuited for cost-effective designs of flyback converters. FSDM07652REWDTU Features • Internal Avalanche-Rugged SenseFET• Advanced Burst-Mode Operation Consumes Under1W at 240VAC & 0.5W load• Precision Fixed Operating Frequency (66kHz)• Internal Start-up Circuit• Improved Pulse-by-Pulse Current Limiting• Over-Voltage Protection (OVP)• Overload Protection (OLP)• Internal Thermal Shutdown Function (TSD)• Auto-Restart Mode• Under-Voltage Lockout (UVLO) with hysteresis• Low Operating Current (2.5mA)• Built-in Soft-Start FSDM07652REWDTU Applications • SMPS for LCD monitor and STB• Adaptor
