Monolithic Power Systems EV2229-Q-00A

Beschreibung

The EV2229-Q-00A is the evaluation board for MP2229, a high-frequency synchronous rectified step-down switch mode converter withinternal power MOSFETs. It offers a very compact solution to achieve 6A continuous output current over a wide input supply rangewith excellent load and line regulation. The MP2229 has synchronous mode operation for higher efficiency over the output current loadrange.Current mode operation provides fast transient response and eases loop stabilization. Full protection features include over-currnt protection and thermal shutdown.The MP2229 requires a minimal number ofreadily-available standard external component and is available in a space saving 3mm x 3mm 14-pin QFN package.
