The SEPIC converter combines the best features of the boost and flyback topologies. making it especially advantageous in high power factor preregulator applications. In addition, ripple current can be steered away from the input, dramatically reduci
XL60XX系列SEPIC恒流产品设计指南,可升降压。The PWM control circuit is able to adjust the duty ratio linearly from 0 to 95%.An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external compo
