Design files

Overview

The PMP7340 uses the TPS53319 synchronous-buck SWIFT converter with integrated power MOSFETs using PowerStack technology  to provide a  highly efficienct, power dense 12V input to 1V output 5.7A solution .   The TPS53319 is ideal for powering low-voltage, high-current  SSD Controller ASICs as well as DDR core memory rail.

Features
  • Small external RC circuit that allows the D-CAP control mode to use low ESR 2x100uF and 1x22uF ceramic output capacitors. 
  • Fast 25us transient response (2.8A to 5.7A load-step)
  • Small 1uH inductor to save space
  • 500kHz switching frequency
  • 86% peak  efficiency from a 12V input to a 1V ouput.
  • No control loop compensation components.
