PMP9131: Fixed frequency voltage mode control is used for CPU, Memory and ASIC applications where a predictable frequency and/or synchrnization to an external clock is needed. Four 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. PMP9131 focuses on ease of electrical testing and ability to make changes "on the fly" thru the PMBus interface. On-board bias supplies and a high speed dynamic load round out the rich test interface.
PMP8832: The PMP8832 reference design uses the UCC28700 primary-side regulated flyback controller to generate a 12V/1.1A output from a universal AC input. The valley switching of the UCC28700 allows this low-cost design to achieve an average efficiency greater than 83%; no load losses are less than 40mW.
PMP7935: The PMP7935 is a single-phase synchronous buck converter module rated for 0.9V output at 45A from an input voltage of 12V. It is used for CPU core power in an enterprise network switching application. The small 1.1"x0.65" module delivers 90% peak efficiency and is smaller and less costly than equivalent multi-phase designs. This modular solution lends itself well to data center equipment where heat generation is increasingly expensive and a high power density is required.
