NCP4200

NCP4200 Programmable Multi-Phase Synchronous Buck Converter with I2C Interface The NCP4200 is an integrated power control IC with an I2C interface. It combines a highly efficient, multi−phase, synchronous buck switching regulator controller with an I2C 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 NCP4200 can be programmed to provide 2−, 3−, or 4−phase operation, allowing for the construction of up to four complementary buck−switching stages. The NCP4200 supports PSI, which is a Power Save Mode. The NCP4200 includes an I2C interface which can b...
