High efficiency 12-V/5-A active clamp forward with wide input range 9-V to 60-V reference design(PMP22075)This forward converter reference design was designed for an isolated 60W intermediate bus voltage rail 12V. It operates in a wide input range 9V to 60V. It features LM5026—100V active clamp current mode PWM controller. A self-driven secondary rectifier with UCC27511 4A/8A driver was used for high efficiency. It is good for isolated supplies where high efficiency and hiccup protection are needed.
- High efficiency 92.2% at 12 Vin
- Wide input range 9 V to 60 V
- Self-driven secondary rectifier improves efficiency
- Hiccup protection enhances reliability
