The NCP81611 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 efficiency at light loads. Dual-edge PWM multiphase architecture ensures fast transient response and good dynamic current balance
