The EV9943-Q-00A is an evaluation board that demonstrates the capabilities of the MP9943, a high-frequency, synchronous, rectified, step-down converter with built-in high-side and low-side power MOSFETs. The MP9943 offers a very compact solution to achieve 3A of peak output current, with excellent load and line regulation over a wide input supply range. The MP9943 has synchronous mode operation for higher efficiency over the output current load range.
Current-mode operation provides fast transient response and eases loop stabilization. Full protection features includes over-current protection and thermal shutdown.
The MP9943 requires a minimal number of readily available, standard external components, and is available in a space-saving QFN-8 (3mmx3mm) package.
