General Description
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.
