基于TOP245Y芯片的反激式多路开关电源设计
Design of a Flyback Swithing Power Supply with Multiple Outputs Based on TOP245Y
Designed a flyback switching power supply with the outputs of 5V/5A, 12V/1A and -12V/1A. peripheral circuits are analyzed by an single-chip switching power supply chip named TOP245Y produced by PI company and the feedback systems composed of TL431 and LTV817. After prototype is developed and tested,Experimental results show that the power efficiency, ripple, output precision to meet the design requirements.
