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.
