The MAX1540 evaluation kit (EV kit) demonstrates the
standard 5A application circuit of the MAX1540. This
DC-DC converter steps down high-voltage batteries
and/or AC adapters, generating precision low-voltage
chipset, dynamic random access memory (DRAM), and
input/output (I/O) power supplies for notebook computers.
The MAX1540 EV kit provides a fixed 1.8V output voltage
(OUT1), a fixed 2.5V output voltage (OUT2), and a
fixed 5V, 100mA linear regulator (LDOOUT) from the 7V
to 24V battery input range. It delivers up to 5A output
current for each output voltage with greater than 90%
efficiency. The EV kit operates at 355kHz/485kHz
switching frequency (OUT2/OUT1, respectively) and
has superior line- and load-transient response.
This EV kit is a fully assembled and tested circuit board.
It also allows the evaluation of other output voltages in
the 0.7V to 5.5V range by changing resistors R21 and
R22 for OUT1, and resistors R19 and R20 for OUT2.
