DESCRIPTION

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.

FEATURES

 2-, 3- or 4-phase Operation

 Channel-Current Balancing
