MAX1549 Evaluation Kit

General Description

Features

The MAX1549 evaluation kit (EV kit) demonstrates the

MAX1549’s standard application circuit. This DC-DC

converter steps down high-voltage batteries and/or AC

adapters, generating precision low-voltage chipset and

RAM power supplies for notebook computers.

♦ 5V to 20V Input Voltage Range

♦ Four Digitally Selectable Operating Voltages

(OUT1)

♦ Dynamically Selectable Output Voltages

0.7V/1.0V/1.3V/1.5V (OUT1, Adjustable from 0.5V

to 2.0V)

The MAX1549 EV kit provides a dynamically adjustable

0.7V to 1.5V output voltage range (OUT1), and a fixed

2.5V output voltage (OUT2) from a 5V to 20V battery

input range. It delivers up to a 6A output current for

OUT1, and up to a 4A output current for OUT2, with

greater than 90% efficiency. The EV kit operates at

300kHz switching frequency and has superior line- and

load-transient response.

♦ Fixed 2.5V Output Voltage (OUT2, Adjustable from

0.5V to 2.7V)

♦ 6A Output Current (OUT1)

♦ 4A Output Current (OUT2)

♦ 300kHz Switching Frequency

♦ Independent Power-Good Outputs

♦ Low-Profile Components

This EV kit is a fully assembled and tested circuit

board. It is capable of evaluating other dynamically

adjustable output voltages in the 0.5V to 2.0V range by

changing R10–R14. Other fixed output voltages in the

0.5V to 2.7V range can be evaluated by changing R20

and R21.

♦ Fully Assembled and Tested
