使用 LM5160 穩壓器的 15W 隔離式自驅同步反相 Fly-Buck 升壓參考設計
PMP10571
概覽
PMP10571 is a sync isolated Flybuck-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 opto-coupler or aux winding, and is capable of achieving good regulation within ±5%. With LM5160's Constan On-Time control, no loop compensation is required, which simplifies the design and helps reducing the external part count and BOM cost.
