Single Output Controller with SVID Interface for Desktop and Notebook CPU Applications NCP81283 The NCP81283 (6 phase) is a single rail, six output buck solution optimized for Intel®’s IMVP9 CPUs.

The multi phase rail control system is based on Dual Edge pulse width modulation (PWM) combined with DCR current sensing.

This provides an ultra fast initial response to dynamic load events and reduced system cost.

The NCP81283 has an ultra low offset cu
