NCP81611规格书详情
Description
The NCP81611 is a multiphase synchronous controller optimized
for new generation computing and graphics processors. The device is
capable of driving up to 4 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 multiphase architecture ensures fast transient
response and good dynamic current balance.
Features
