The MAX8707 is a multiphase (3-/4-phase), interleaved, fixed-frequency, step-down controller for AMD Hammer CPU core supplies.

Interleaved multiphase operation reduces the input ripple current and output voltage ripple while easing component selection and layout placement.

The MAX8707 includes active voltage positioning with adjustable gain and offset, reducing power dissipation and bulk output-capacitance requirements.

dedicated differential currentsense inputs for each phase and includes a fifth pair of current-sense inputs to provide an accurate voltagepositioning slope and average current-limit protection using a single current-sense resistor. The MAX8707 also has two dedicated inputs that provide differential remote voltage sensing. The MAX8707 provides an analog input for setting the suspend voltage and a slew-rate controller for transitions between VID codes or the suspend voltage. The controllers reduce.
