MAX619 EV

Evaluation Kit Information
_______________General Description
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.
_________________________Quick Start
The MAX619 EV Kit is fully assembled and tested.
Follow the steps below to verify board operation.
Do not turn on the power supply until all connec-
tions are completed.
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 power and verify that the output is
5V 4%.
