Beschreibung
The PMP10535 reference design is a low profile quad 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 four isolated outputs of ±5V, ±12V, 75mA 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 Fly-Buck 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 constan on-time control, no loop compensation is required, which simplifies the design and helps reducing the external part count and BOM cost.
