MAX1549

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 R10R14. Other fixed output voltages in the 0.5V to 2.7V range can be evaluated by changing R20 and R21.
