MP2930
4-Phase PWM Controller
With 8-Bit DAC code for VR10 and VR11
DESCRIPTION
FEATURES
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.
2-, 3- or 4-phase Operation
Channel-Current Balancing
Voltage Droop vs. Load Current
Precision Resistor or DCR Current Sensing
8-Bit ID Input with Selectable Between VR11
and VR10 Code at 6.25mV Per Bit
Adjustable Switching Frequency
Over Current Protection
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.
Over Voltage Protection
Available in a 40-pin QFN6x6 Package
APPLICATIONS
8-bit ID input with selectable VR11 code and
extended VR10 code can set output voltage
dynamically.
Power Modules
Desktop, Server, Core Voltage
POLs (Memory)
The MP2930 also provides accurate and reliable
over current protection and over voltage
protection.
