MAX8771 Description
The MAX8770/MAX8771/MAX8772 are 2/1-phase interleaved Quick-PWM™ step-down VID power-supply controllers for notebook CPUs. True out-of-phase operation reduces input ripple current requirements and output voltage ripple while easing ponent selection and layout difficulties. The Quick-PWM control provides instantaneous response to fast load current steps.
