MAX8707 is a multiphase (3/4 phase) PWM controller for AMD Hammer CPU core power supply. Multiphase interleaved operation reduces input current ripple and output voltage ripple while simplifying component selection and layout design. MAX8707 includes active voltage positioning function with adjustable gain and offset to reduce power consumption and the requirement for large output capacitors.
The MAX8707 is a 40‑pin thin QFN power‑management chip designed for AMD Hammer CPUs. It provides multiple voltage‑regulation options, selectable switching frequencies, and fault‑protection features for high‑performance computing platforms.
The document contains absolute maximum ratings, detailed electrical characteristics, efficiency curves, pin‑out diagrams, and mechanical package dimensions, enabling designers to integrate the device into industrial and commercial systems. This manual is written in Chinese.
