MP2229GQ-P Monolithic Power Systems

MP2229 High Efficiency 21V, 6A Synchronous Step-Down Converter with External Sync, Low-Power Mode, and External Soft-Start DESCRIPTION FEATURES The MP2229 is a high-frequency, synchronous, Wide 4.5V to 21V Operating Input Range rectified, step-down, switch-mode converter 6A Output Current with internal power MOSFETs. It offers a Low 40m /18m R of Internal Power DS(ON) compact solution to achieve a 6A continuous MOSFETs output current over a wide input-supply range Programmable Switching Frequency with excellent load and line regulation. The Frequency SYNC from 300KHz to 2MHz MP2229 has synchronous-mode operation for External Clock higher efficiency over the output current load Low-Power Mode Selectable by an External range. Signal Current-mode operation provides fast transient External Soft-Start response and eases loop stabilization. Full Pre-Bias Start-Up protection features include over-current OCP with Hiccup Mode protection (OCP) and thermal shutdown (TSD). Thermal Shutdown Output Adjustable from 0.6V The MP2229 requires a minimal number of Available in a QFN-14 (3mmx3mm) readily available, standard, external Package components and is available in a space-saving 3mm x 3mm 14-pin QFN package.
