Description
General part information
MP4423 Series
The MP4423 is a high-frequency, synchronous, rectified, step-down, switch-mode converter with built-in power MOSFETs. It offers a very compact solution to achieve a 3A continuous output current with excellent load and line regulation over a wide input supply range. The MP4423 has synchronous mode operation for higher efficiency over the 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 MP4423 requires a minimal number of readily-available standard external components, and is available in a space-saving QFN-8 (3mmx3mm) package.Wide 4V to 30V Continuous Operating Input Range 36V Input Transient Tolerance for Automotive Load Dump 85m?/55m? Low RDS(ON) Internal Power MOSFETs High-Efficiency Synchronous Mode Operation Default 410kHz Switching Frequency Synchronizes to a 200kHz to 2.2MHz External Clock High Duty Cycle for Automotive Cold-crank Power-Save Mode Internal Soft-Start Power Good OCP Protection and Hiccup Thermal Shutdown Output Adjustable from 0.8V Available in an QFN-8 (3mmx3mm) package
