Referenzdesign von: Texas Instruments
PMP4478, AC input, 5V/3A Quasi-resonant Flyback Converter with Optimized Light Load Efficiency Reference Design. The PMP4478 is an optimized reference design for appliance applications which provides high current. Low ripple/noise < 50mV is achieved via Pi type filter at the output. The design also achieves good light load efficiency with optimized transformer design. When the load is 300mW, the input power can still be limited to less than 420mW
