Evaluation Tools

The EV9151-D-00A is for demonstrating MPS’s MP9151, a high-frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. MP9151 offers a very compact solution to achieve 4A continuous output current over a wide input supply range with excellent load and line regulation. The MP9151 operates at high efficiency over a wide output current load range.
Current-mode operation provides fast transient response and eases loop stabilization. The full protection features include over-current protection and thermal shutdown.
The MP9151 requires a minimal number of readily-available standard external components and comes in a space saving 2×3mm 14-pin QFN package.
