Overview

NCP81274 8/7/6/5/4/3/2/1 Phase Buck Controller with PWM_VID and I2C Interface The NCP81274 is a multiphase synchronous controller optimized for new generation computing and graphics processors.
The device is capable of driving up to 8 phases and incorporates differential voltage and phase current sensing, adaptive voltage positioning and PWM_VID interface to provide and accurately regulated power for computer or graphic controllers.
The integrated power saving interface (PSI) allows for the processors to set the controller in one of three modes, i.
e.
all phases on, dynamic phases shedding or fixed low phase count mode, to obtain high efficiency in light-load conditions.
The dual edge PWM mu...
