The NCP81276 is a multiphase synchronous controller optimized for next-generation computing and graphics processors. Capable of driving up to 4 phases, the device integrates differential voltage and phase current sensing, adaptive voltage positioning, and a PWM_VID interface to provide accurately regulated power to a computer or graphics controller. An integrated Power Saving Interface (PSI) allows the processor to set the controller into one of three modes, all phases on, dynamic phase shedding, or fixed low phase count mode for high energy efficiency at light loads. Dual-edge PWM multiphase architecture ensures fast transient response and good dynamic current balance
