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.

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.

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.
