4.5V to 28V Input, Synchronous PWM Buck Controllers

for DDR Termination and Point-of-Load Applications

General Description

Features

The MAX8553 is a 4.5V to 28V input-voltage, synchro-

nous step-down controller that provides a complete

power-management solution for DDR memory. The

ꢀ Up to 25A Output-Current Capability

ꢀ Quick-PWM Control for Fast Loop Response

ꢀ Up to 95% Efficiency

MAX8553 generates 1/2 V

voltage for VTT and

REFIN

VTTR. The VTT and VTTR tracking voltages are main-

tained within 1% of 1/2 V . The MAX8554 is a 4.5V to

ꢀ 4.5V to 28V Input Voltage Range

REFIN

28V input voltage, nontracking step-down controller with

a low 0.6V feedback threshold voltage. The MAX8553/

MAX8554 use Maxim’s proprietary Quick-PWM™ archi-

tecture for fast transient response and operate with

selectable pseudo-fixed frequencies. Both controllers

can operate without an external bias supply.

ꢀ No External Bias Supply Required

ꢀ 0 to 3.6V Input REFIN Range (MAX8553)

ꢀ Automatically Sets VTT and VTTR to within 1%

of 1/2 V

- (MAX8553)

REFIN

ꢀ Low 0.6V Feedback Threshold (MAX8554)

The controllers operate in synchronous-rectification mode

to ensure balanced current sourcing and sinking capabili-

ty of up to 25A. The MAX8553/MAX8554 also provide up

to 95% efficiency, making them ideal for server and point-

of-load applications. Additionally, a low 5µA shutdown

current allows for longer battery life in notebook applica-

tions. Lossless current monitoring is achieved by monitor-

ing the low-side MOSFET’s drain-to-source voltage. The

MAX8553/MAX8554 have an adjustable foldback current

limit to withstand a continuous output overload and short

circuit. Digital soft-start provides control of inrush current

during power-up. Overvoltage protection shuts the con-

verter down and discharges the output capacitor. The

MAX8553/MAX8554 come in space-saving 16-pin QSOP

packages.
