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.
