The MAX619 evaluation kit (EV kit) is a 3V to 5V charge-

pump DC-DC converter capable of driving loads up to

50mA. The circuit consists of the SOIC and four surface-

mount capacitors on a single-layer printed circuit board.

♦ 2.0V to 3.6V Input Range

♦ Up to 50mA Output Current

♦ 1µA Shutdown Current

Surface Mount

Do not turn on the power supply until all connec-

tions are completed.

MAX619EV

1. Connect a 2V to 3.6V supply to the pad marked VIN.

The ground connects to the GND pad.

2. Connect a voltmeter and load (if any) to the VOUT

pad.

3. Place the shunt on JU1 across the ON side. This

grounds the SHDN pin to enable the device. Moving

the shunt to the OFF side connects SHDN to VIN to

disable the device. Remove the shunt if an external

signal is connected to the SHDN pad.

4. Turn on the p owe r a nd ve rify tha t the outp ut is

5V ± 4%.
