General Desc ription
The MAX881R IC is an inverting, charge-pump DC-DC
converter with a low-noise, regulated output. Low out-
put ripple voltage makes this device ideal for biasing
the GaAsFETs commonly found in cellular telephone
transmitters.
The MAX881R evaluation kit (EV kit) is a fully assem-
bled and tested surface-mount board. Provisions are
made for mounting a second voltage-divider resistor,
which is required for setting output voltages other than
-2V. A special scope-probe socket is also mounted on
the board, so output noise can be observed on an
oscilloscope.

Quic k S tart
The MAX881R 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 2.5V to 5.5V supply to the pad labeled
VIN. Connect the ground lead to the pad labeled
GND.
2) Connect a voltmeter and the load to the VOUT pad.
3) Make sure there is no shunt across J U1.
4) Turn on the power and verify that the output is -2V.
You can insert a scope probe into J 1 to observe the
output noise. Be sure the scope ground makes con-
tact with the outside of the connector.
