MAX1833 Evaluation Kit
General Description
Features
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-
o Reverse-Battery Protection
o 1.5V to V
Input Supply Voltage
OUT
o 3.3V Output Voltage (MAX1833/MAX1835)
tive input voltage between 1.5V to V
and converts it
OUT
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.
o Adjustable Output Voltage (MAX1832/MAX1834,
2V to 5.5V)
o Up to 150mA Output Current
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.
o No External Schottky Diode Required
o Synchronous Rectification for Improved
Efficiency
o 1µA IC Shutdown Current
o RST Output (MAX1833/MAX1835)
o 6-Pin SOT23 Package
o Surface-Mount Construction
o Fully Assembled and Tested
