General Description
The MAX1800 evaluation kit (EV kit) accepts 1.8V to
5.5V battery voltages and provides all of the output volt-
ages required in digital still cameras (DSC). The EV kit
consists of the MAX1800 multi-output master converter
and the MAX1801 slave step-up converter.
The EV kit provides 10 separate output voltages. The
MAX1800 provides one main-system step-up converter
(3.3V/400mA), one linear regulator for the DSP core
(1.8V/200mA), one step-up converter for the backlight
(7V/100mA), three flyback outputs for the CCD
(14.3V/10mA, 5V/50mA, -8.15V/10mA), and three fly-
back outputs for the LCD (13.85V/10mA, 5V/50mA,
-16.23V/10mA). In addition, the MAX1801 provides one
step-up converter for the motor (5V/500mA).
The EV kit’s outputs are adjustable and are suitable for
applications running from 2- or 3-cell alkaline, NiCd, or
NiMH batteries or from a single lithium-on (Li+) battery.
