PMP9726

12Vin, 1.2V/1.7A Low Cost, Small Form Factor, Synchronous Buck Reference Design

PMP9726

Design files

Overview

This reference design generates a 1.2V output from a 12V input, using the TPS562209 synchronous buck converter.  This converter uses the DCAP2 control method to minimize output capacitance while eliminating feedback compensation components and still providing an excellent load transient response.  The converter switches at 650kHz.  The peak efficiency of this design is 83%.

Features
  • Ready to use DC/DC solution for 1.7A
  • Very generic design
Personal electronics

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
