FEATURES
Internal Avalanche-Rugged SenseFET Advanced Burst-Mode Operation Consumes Under DESCRIPTION
The PWM controller includes an integrated fixed-frequency oscillator, undervoltage 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. 1W 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...
