PMP9131, High Density 160-A (210-A peak), 4-Phase DC-DC Buck Converter with PMBUs Interface Reference Design

PMP9131, High Density 160-A (210-A peak), 4-Phase DC-DC Buck Converter with PMBUs Interface Reference Design. 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. 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
