Maxim MAX8553/MAX8554 Datasheet
The MAX8553 and MAX8554 are synchronous buck regulators that operate from a 4.5 V to 28 V input range and deliver up to 25 A of balanced source current. They are designed for DDR memory power‑management in servers, laptops, storage systems and other high‑performance applications.
Key features include Quick‑PWM control for fast transient response, selectable switching frequencies (200 kHz‑550 kHz), up to 95 % efficiency, and a compact 16‑pin QSOP package. The devices provide integrated VTT/VTTR tracking, adjustable fold‑back current limit, digital soft‑start, and over‑voltage protection. This manual is written in Chinese.
