Description

The PMP10745 is a dual output DC/DC Buck converter power supply reference design for USB charging applications. It takes a 7V to 36V input voltage, and generates two 5V at 3A outputs with 96% peak efficiency. The reference design features two LMR23630 buck converters to provide two very stable and well-regulated outputs. The board dimension is 66 x 58 mm (2.6 x 2.3 inch), but the solution size is 46 x 38 mm (1.8 x 1.5 inch). The reference design uses an EMI filter at the input and the board is layout-optimized for improved EMI performance, which results in compliance with the CISPR 25 Class 5 conducted emissions standard.

Features
  • Input: 7V to 36V
  • Output: 5V @ 3A, 5V @ 3A
  • Peak efficiency 96%
  • EMI CISPR 25 Class 5
  • Compact solution size, 1.8 x 1.5 inch
