Description

The EVQ28261-L-00A is for demonstrating MPS’s MPQ28261, a high frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs. MPQ28261 offers a very compact solution to achieve 3A continuous output current over a wide input supply range with excellent load and line regulation. The MPQ28261 operates athigh efficiency over a wide output current load range.

Current mode operation provides fast transient response and eases loop stabilization. The full protection features include OCP and thermalshutdown.

The MPQ28261 requires a minimum number of readily available standard external components and comes in a space saving 3x4mm 14-pinQFN package.
