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.
