NCP4201

Programmable Multi-Phase

Synchronous Buck

Converter with PMBus

The NCP4201 is an integrated power control IC with a PMBus

interface. It combines a highly efficient, multi−phase, synchronous

buck switching regulator controller with a PMBus interface, which

enables digital programming of key system parameters to optimize

system performance and provide feedback to the system.

It uses an internal 8−bit DAC to read a Voltage Identification (VID)

code directly from the processor, which is used to set the output

voltage between 0.375 V and 1.6 V.

QFN40 6x6

CASE 488AR

This device uses a multi−mode PWM architecture to drive the

logic−level outputs at a programmable switching frequency that can

be optimized for VR size and efficiency. The NCP4201 can be

programmed to provide 2−, 3−, or 4−phase operation, allowing for the

construction of up to four complementary buck−switching stages. The

NCP4201 supports PSI, which is a Power Save Mode.

AWLYYWWG

The NCP4201 includes a PMBus interface which can be used to

program system set points such as voltage offset, load−line and phase

balance and output voltage. Key system performance data, such as

CPU current, CPU voltage, and power and fault conditions can also be

read back over the PMBus from the NCP4201.
