PMP7917 is a dual output flyback converter capable of 40W output power. This design uses the LM5021-1 current-mode PWM controller. The operating input voltage range is 40V to 60. The outputs are 6V at 4.33A and 4V at 3.5A. Self-driven synchronous operation is employed for the secondary rectifiers, resulting in good cross regulation.
