MAX685EVKIT

Features of the MAX685EVKIT are:(1)+15V positive output voltage;(2)-7.5V negative output voltage;(3)2.7V to 5.5V battery input voltage;(4)10mA output current;(5)single inductor for both outputs;(6)0.1A shutdown current;(7)200kHz or 400kHz fixed frequency;(8)power-OK output;(9)surface-mount,low-profile components;(10)fully assembled and tested.

The MAX685EVKIT is fully assembled and tested.Follow these steps to verify board operation. Do not turn on the power supply until all connections are completed.(1)connect a +2.7V to +5.5V power supply to the VIN pad. connect ground to the GND pad;(2)connect voltmeters and loads,if any, to the +VOUT and VOUT- pads;(3)verify that the shunts are on JU1, JU2, and JU3 across pins 2 and 3;(4)turn on the power supply and verify the positive output voltage is +15V and the negative output is -7.5V;(5)for other output voltages, refer to the setting the output voltage section in the MAX685 data sheet for instructions on selecting the feedback resistors.
