NCP4206 Datasheet | onsemi

VR11.1 Digital Programmable Multi-Phase Synchronous Buck Converter with SMBus The NCP4206 is an integrated power control IC with a SMBus interface. The NCP4206 is a highly efficient, multiphase, synchronous buck switching regulator controller, which aids design of High Efficiency and High Density solutions. The NCP4206 can be programmed for 1- , 2- , 3- , 4- , 5- or 6 phase operation, allowing for the construction of up to 6 plementary buck switching stages. The NCP4206 supports PSI, which is a power state indicator and can be used to reduce the number of operating phases at light loads. The SMBus interface enables digital programming of key system parameters to optimize system performance and provide feedback to the system. The NCP4206 has a built in shunt regulator that allows the part to be powered from the +12 V system supply through a series resistor. The NCP4206 is specified over the extended mercial temperature range of 0°C to +85°C and is available in a 48 Lead QFN package.
