Reference Design for 12Vin: Two Phase Synchronous Buck Converter 1V 50A with PMBus Control
Description
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 lossesFixed frequency voltage mode control allows for user selection of switching frequency and synchronization to an external clockOutput voltage: current limit and fault thresholds/responses can be adjusted on the fly" through the PMBus interfaceFocus of evaluation board is on compactness of power stages including inductorsRich test interface including PMBus socket: and high speed dynamic test loadSchematic: BOM: layout and Test Report focusing on thermal performance & load dynamics"
