12V to 1V 30A Voltage Mode Synchronous Buck Converter with PMBus Control Reference Design (PMP20023)

Fixed frequency voltage mode control is used for communications and computing applications where a predictable frequency and / or synchronization to an external clock is needed. With control and power in one IC and inductor on top of the IC with its raised leads, a very small size solution is achieved. PMP20023 focuses on ease of electrical testing and ability to make changes "on the fly" thru the PMBus interface. A high speed dynamic load rounds out the rich test interface.

Возможности

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" thru the PMBus interface Focus of evaluation board is on compactness of design with inductor on top of converter Rich test interface includes PMBus socket, Bode plot test points and high speed dynamic test load Schematic, BOM, layout and Test Report focusing on control loop & load dynamics for both 600mVout and 1.0Vout
