Overview

The PMP20080 is a powerful design intended to operate 5 output rails with application to a Hybrid Memory Cube (HMC) Gen2. This design uses 5 synchronous bucks with multiple different controllers to allow for a well regulated set of outputs. Also, PMP20080 allows for the configurability that comes along with PMBus. The PMP20080 reference design has been designed entirely with standard components.

Features
  • 12VC input, 0.9V output at 15.5A, 1.2V output at 12.5A
  • PMBus configurability
  • Utilize all standard components (including magnetics)
  • Test report available
