MAX8550 Evaluation Kit

General Description

Features

♦ VDDQ Preset to 2.5V/12A

The MAX8550 evaluation kit (EV kit) is designed to evalu-

ate the MAX8550 DDR power-supply solution for note-

books, desktops, and graphics cards. The EV kit board

produces VDDQ at the output of the synchronous PWM

buck, VTT at the output of the sourcing/sinking LDO linear

regulator, and VTTR at the output of the reference buffer.

♦ VTT 1.25V Source/Sink 1.5A Continuous/3A Peak

♦ VTTR 1.25V Source/Sink 10mA

♦ VIN Range: 9V to 20V

♦ Optimized Switching Frequency: 600kHz

♦ Overvoltage/Undervoltage Protection

♦ Standby

The VDDQ output is preset to 2.5V and sources up to

12A. The VTT output is always VDDQ/2 and can

source/sink up to 3A of peak current and 1.5A of contin-

uous current. The VTTR output is also always VDDQ/2

and can source/sink up to 10mA.

♦ Independent Shutdown

The MAX8550 EV kit was conveniently designed with

jumpers to select the OVP/UVP, TON, SKIP, STBY, and

SHDN_ modes. The board’s default settings enable

OVP (overvoltage protection), 600kHz switching fre-

quency, low-noise PWM mode, VDDQ, VTT, and VTTR.

♦ Power OK

Note: To evaluate the MAX8550A, request a free sample of the

MAX8550AETI when ordering the MAX8550 EV kit. To evaluate

the MAX8551, request a free sample of the MAX8551ETI when

ordering the MAX8550 EV kit.

The EV kit comes with the MAX8550 installed. Contact

the factory for free samples of the MAX8550A or

MAX8551 to evaluate these parts.
