Product Details

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 positive 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.

Applications

Battery Backup
Cordless Phones
Digital Still Cameras
Handheld Instruments (PDAs, Palmtops)
Local 3.3V to 5V Supplies
Medical Diagnostic Equipment
Pagers
PC Cards
Remote Wireless Transmitters
