NCP4201 Datasheet
NCP4201
Programmable Multi-Phase
Synchronous Buck
Converter with PMBusThe 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 V oltage Identification (VID)
code directly from the processor, which is used to set the output
voltage between 0.375 V and 1.6 V. 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.
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.
The NCP4201 is specified over the extended commercial
temperature range of 0°C to +85°C and is available in a 40 Lead QFN
package.
