Texas Instruments LM5017MRX/NOPB | Demoboard PMP10558

Description

The PMP10558 reference design is a low profile triple output isolated Fly-Buck power supply for industrial applications. The power supply has a synchronous buck regulator, LM5017, and a low profile (6mm) transformer. It generates three isolated outputs depending on the transformer selection. The LM5017 is a 100V wide Vin, 600mA synchronous buck regulator. The input voltage range of the design is 18V to 30V, making it suitable for 24V input industrial applications. The Fly-Buck can regulate the secondary side outputs without an opto-coupler or auxillary winding and is capable of achieving good cross regulation within ±5%. With LM5017's constant on-time control, no loop compensation is required, which simplifies the design and helps reduce the external part count and BOM cost.
