Description

The PMP11414 reference design features TPS65400 quad 4/4/2/2A output point-of-load in a tiny 0.65"x0.875" solution size (16.5mmx22.2mm). TPS65400 fully integrates four buck regulators into a small 7mmx7mm QFN package. It also has PMBus capability for flexible control and configuration.  The PMP11414 demonstrated high efficiency as well as intelligence for flexible margining and sequencing functions.

Features
  • 7V to 14V in, 1.2Vout @ 4A, 1.8V@4A, 2.5V@2A and 3.3V@2A
  • Total solution size: 0.65"x0.875" (16.5mmx22.2mm)
  • Peak efficiency 91%
  • Switching frequency 500kHz
  • PMBus enabled margining and sequencing
