NCP81274: Multi-Phase Synchronous Buck Controller with Power Saving Mode and PWM VID Interface

Description: The NCP81274 is a multiphase synchronous controlle...
  • 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 multiphase architecture ensures fast transient response and good dynamic current balance.
