MAX1565 Evaluation Kit
General Description
The MAX1565 evaluation kit (EV kit) is a fully assembled
and tested circuit board that accepts 1.5V to 3.6V input
voltages and provides all the output voltages required
for a typical digital still camera. The outputs consist of
the main step-up output (3.35V), a step-down output
(1.5V), a general-purpose 5V output, two outputs for
charge-coupled device (CCD) and LCD bias, and an
optional general-purpose output using the MAX1801
slave controller.

Quick Start
Follow the steps below to verify operation of the
MAX1565 EV kit.
Do not turn on the power supply until
all connections are completed:
1) Connect a series LED array or install surface-mount
white LEDs in D7鈥揇10. When connecting an LED
array, connect the anode to LEDOUT+ and connect
the cathode to LEDOUT-.
2) Preset the power supply to between 1.5V and 3.6V.
3) Turn off the power supply.
4) Connect the power-supply positive lead to IN.
5) Connect the power-supply ground lead to GND.
6) Connect loads from outputs OUTSD, OUT1, OUT3A,
and OUT3B to GND. See Table 1 for maximum load
currents.
7) To enable the main step-up output, verify that JU1
has pins 2 and 3 shorted.
8) Verify that JU2鈥揓U8 have pins 1 and 2 shorted.
9) Turn on the power supply.
10) Use a voltmeter to verify the OUTSU voltage (3.35V).
11) Connect a load, if desired, from OUTSU to GND.
See Table 1 for maximum load currents.
12) To verify other outputs, move JU2鈥揓U5 to short pins
2 and 3. Use a voltmeter to verify output voltages.
