Product Details

The MAX685 evaluation kit (EV kit) provides dual-output +15V and -7.5V voltages from 2.7V to 5.5V input voltage. Each output regulates separately, and each can deliver 10mA output current. Both output voltages can be adjusted by changing the feedback resistor values.

The MAX685 EV kit provides low quiescent current and high efficiency for maximum battery life. The EV kit operates at a fixed 200kHz or 400kHz frequency, which allows the use of a tiny surface-mount inductor. This EV kit is a fully assembled and tested surface-mount circuit board.
