PMP10559 Reference Design

Texas Instruments

20W Industrial Power Supply


PMP10559 is a non-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 design accepts an input voltage of 18V to 30V: and outputs 30V: capable of providing 0.67A 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.
