The NCP4208 is an integrated power control IC with a PMBus 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 PMBus interface enables digital programming of key system parameters to optimize system performance and provide feedback to the system. The NCP4208 has a built in shunt regulator that allows the part to be powered from the +12 V system supply through a series resistor. The NCP4208 is specified over the extended commercial temperature range of 0°C to +85°C and is available in a 48 Lead QFN package. |
