Description
The MAX629 evaluation kit (EV kit) contains two separate switching-regulator circuits. The first circuit converts a +0.8V to VOUT battery voltage to a +24V LCD backplane bias voltage for currents up to 20mA. The second circuit converts a +0.8V to +12V battery voltage to a -20V voltage for currents up to 20mA. The MAX629 requires a +2.7V to +5.5V supply at VCC, but the inductor can be powered from as low as 0.8V. Both output voltages can be adjusted by changing the feedback-resistor values.
The MAX629 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. This EV kit is a fully assembled and tested surface-mount circuit board.
