概要

The MP2930 is a 4-phase, synchronous buck switching regulator controller for regulating microprocessor core voltage. MP2930 also uses dual edge PWM mode to realize fast load transient with fewer capacitors. For meeting the requirement of microprocessor output voltage drops tightly as load current increases, output current is sensed to realize voltage droop function. Accurate current balancing is included in MP2930 to provide current balance for each channel. 8-bit ID input with selectable VR11 code and extended VR10 code can set output voltage dynamically. The MP2930 also provides accurate and reliable over current protection and over voltage protection.
