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.
Features
- 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
