MAX1833 Evaluation Kit
General Description
The MAX1833 evaluation kit (EV kit) evaluates the
MAX1833 high-efficiency, step-up DC-DC converter for
portable hand-held devices. The EV kit accepts a posi-
tive input voltage between 1.5V to V
OUT
and converts it
to a 3.3V output for currents up to 150mA. The EV kit
provides ultra-low quiescent current and high efficiency
for maximum battery life.
The MAX1833 EV kit is a fully assembled and tested
surface-mount printed circuit board. It can also be used
to evaluate the MAX1832/MAX1834/MAX1835 for other
output voltages in the 2V to 5.5V range. Additional pads
on the board accommodate the external feedback
resistors for setting different output voltages.
