NCP4201 Datasheet | onsemi

Programmable Multi-Phase Synchronous Buck Converter with PMBus The NCP4201 is an integrated power control IC with a PMBus interface. It bines 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. 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 plementary buck- switching stages. The NCP4201 supports PSI, which is a Power Save Mode. The NCP4201 includes a PMBus interface which can be...
