PMP10571, 15W Industrial Power Supply Reference Design

PMP10571, 15W Industrial Power Supply Reference Design. PMP10571 is a sync isolated Fly-Buck-boost converter with a negative primary voltage. The power supply has a synchronous buck regulator, LM5160, and a versa pack transformer. The synchronous rectifier on the secondary improves efficiency and regulation under heavy load. The design accepts an input voltage of 18V to 30V and outputs 5V, capable of providing 3A of current to the load, making it suitable for 24V input industrial application. The Fly-Buck topology can regulate the secondary side outputs without Optocoupler or aux winding, and is capable of achieving good regulation within ±5%
