Specifications of MAX1678EVKIT

Output Voltage
3.3 V
Output Current
45 mA
The MAX1678 evaluation kit (EV kit) provides a regulated
3.3V output while operating on input voltages as low as
0.7V with guaranteed start-up at 0.87V. The input source
can be a 1 or 2-cell battery or a DC supply. Efficiency is
typically 90% with output loads up to 100mA.
The kit uses surface-mount components and is fully
assembled and tested for quick evaluation. Jumpers
are provided for selecting an adjustable output voltage
and for shutdown control.
