The MAX686 evaluation kit (EV kit) is a fully assembled and tested surface-mount circuit board that contains two separate switching-regulator circuits. The first circuit converts a +0.8V to +18V battery voltage to a +18V LCD bias voltage for currents up to 20mA. The second circuit converts a +0.8V to +12V battery voltage to a-17V voltage for currents up to 20mA.
The MAX686 requires a +2.7V to +5.5V supply at VIN, but the inductor can be powered from as low as +0.8V. The device features an internal N-channel MOSFET switch, programmable current limit, and internal 6-bit DAC for digital adjustment of the output voltage. The MAX686 EV kit provides low quiescent current and high efficiency for maximum battery life. Operation up to 300kHz allows the use of a tiny surface-mount inductor.
