The MAX8554EEE+ from Analog Devices is a synchronous step-down PWM buck controller. It is designed for DDR memory power supplies and point-of-load applications, offering a complete power management solution.
This controller features a wide input voltage range of 4.5V to 28V and can deliver up to 25A of output current. It utilizes Maxim's proprietary Quick-PWM™ architecture for fast transient response and achieves up to 95% efficiency. The device operates with selectable pseudo-fixed frequencies, including 200kHz, 300kHz, 400kHz, and 550kHz.
Key features include a low 0.6V feedback threshold voltage, adjustable foldback current limit for overload and short-circuit protection, and digital soft-start for controlled inrush current. Overvoltage protection is also integrated. The MAX8554EEE+ is supplied in a space-saving 16-pin QSOP package, suitable for surface mounting.
Applications include wide-input power supplies, servers, storage, ASIC and CPU core voltages, notebook and LCD-PC power supplies, and DDR I and DDR II memory power supplies.
