Low Profile Quad Output Isolated Fly-Buck Power Supply for Industrial Application Reference Design
Description
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: which simplifies the design and helps reduce the external part count and BOM cost.
Features
- Multiple isolated bias power using Fly-Buck: ideal for PLC and industrial applications 2W output power: +/-15V: +/-5V @ 50mA each: with LM5017 capable of 7.5V to 100V input Primary Side Regulation without Opto: Good Cross Regulation: within +/-5% Less than 6mm low profile transformer Constant On Time Control: No Loop Compensation Required: and Fast Transient Response This circuit board is tested: and the design files and test report are included
