NCP4208 VR11.1 Digital Programmable 8-Phase Synchronous Buck Converter with I2C Interface The NCP4208 is an integrated power control IC with an I2C interface. The NCP4208 is a highly efficient, multiphase, synchronous buck switching regulator controller, which aids design of High Efficiency and High Density solutions. The NCP4208 can be programmed for 1−, 2−, 3−, 4−, 5−, 6−, 7− or 8−phase operation, allowing for the construction of up to 8 complementary buck switching stages. The NCP4208 supports PSI, which is a power state indicator and can be used to reduce the number of operating phases at light loads. The I2C interface enables digital programming of key system parameters to optimize system performance and provide feedback to the system.
