MAX1802 Evaluation Kit
for Digital Still Cameras
General Description
The MAX1802 evaluation kit (EV kit) accepts +3.3V to
+11V battery voltages and provides all of the output volt-
ages required in digital still cameras (DSC). This EV kit
consists of the MAX1802 multi-output master converter
and the MAX1801 slave step-up converter.
The MAX1802 EV kit provides 10 separate output volt-
ages. The MAX1802 provides one main system step-
down converter (+3.3V/1A), one DSP core step-down
(+1.8V/400mA), one step-up converter for the backlight
(+7V/100mA), three flyback outputs for the CCD, and
three flyback outputs for the LCD. In addition, the
MAX1801 provides one general-purpose step-up con-
verter (+12V/100mA).
The MAX1802 EV kit’s outputs are adjustable and are
suitable for applications running from 4-cell alkaline,
NiCd, or NiMH batteries, or from lithium ion (Li+) batter-
ies (1 or 2 cell).
