This forward-converter reference design is designed for an isolated 60-W, 12-V intermediate bus voltage rail. It operates in a wide-input range of 9 V to 60 V. The design features LM5026, a 100-V active clamp current mode PWM controller. A self-driven secondary rectifier with UCC27511 4-A and 8-A driver is used for high efficiency. It can be used in isolated-supply applications where high efficiency and hiccup protection are needed.
