Product Description

The MP1499 is a high frequency synchronous rectified step-down switch mode converter with built in internal power MOSFETs. It offers a very compact solution to achieve 5A peak output current over a wide input supply range with excellent load and line regulation. The MP1499 has synchronous mode operation for higher efficiency over output current load range. Current mode operation provides fast transient response and eases loop stabilization. Full protection features include over current protection and thermal shut down. The MP1499 requires a minimum number of readily available standard external components and is available in a space saving 10-pin QFN (2x3mm) package.

High-Efficiency, 5A Peak, 16V, 500kHz Sync. Step-Down Converter Evaluation Board

The EV1499-D-00A demonstrates MPS’s MP1499, a high-frequency, synchronous, rectified, step-down converter with built-in high-side and low-side power MOSFETs. The MP1499 offers a very compact solution to achieve a 5A peak output current with excellent load and line regulation over a wide input supply range. The MP1499 has synchronous mode operation for higher efficiency over the output current load range.

Current-mode operation provides fast transient response and eases loop stabilization.

Protective features include over-current protection and thermal shutdown.

The MP1499 is available in a space saving 10-pin QFN (2×3mm) package.
