Design files

Overview

Fixed frequency voltage mode control is used for CPU, Memory and ASIC applications where a predictable frequency and/or synchronization to an external clock is needed.  Two high current synchronous power stages provide the high currents and low losses needed for these applications. Multi-phase also allows output ripple cancellation and effective higher bandwidth control for a given switching frequency. PMP11196 focuses on ease of electrical testing and ability to make changes "on the fly" through the PMBus interface. A high speed dynamic load rounds out the rich test interface.

Features
  • Two fully synchronous power stages for high currents & lowest losses
  • Fixed frequency voltage mode control allows for user selection of switching frequency and synchronization to an external clock
  • Output voltage, current limit and fault thresholds/responses can be adjusted "on the fly" through the PMBus interface
  • Focus of evaluation board is on compactness of power stages including inductors
  • Rich test interface including PMBus socket, and high speed dynamic test load
  • Schematic, BOM, layout and Test Report focusing on thermal performance & load dynamics
