Low Profile Quad Output Isolated Fly-Buck Power Supply for Industrial Application Reference Design (PMP9478)

The PMP9478 reference design is a low profile quad output isolated Flybuck power supply for industrial applications. The power supply has a synchronous buck regulator, LM5017, and a low profile (6mm) transformer. It generates four isolated outputs of ±5V, ±15V, 50mA each. The LM5017 is a 100V wide Vin, 600mA synchronous buck regulator. The input voltage range of the design is 20V to 32V, making it suitable for 24V input industrial application. The Flybuck can regulate the secondary side outputs without opto-coupler or aux winding, and is capable of achieving good cross regulation within ±5%. With LM5017's Constant On-Time control, no loop compensation is required, whichsimplifies the design and helps reduce the external part count and BOM cost.
