Description
The RPX-1.0-EVM-1 generates a constant output voltage selectable from 0.8V, 1.8V, 3.3V,
5V, 12V, 15V, or 24V from a DC input in the range of 4-36V. It has a maximum continuous output
current of 1A.
All the functions of the RPX-1.0 such as output voltage selection, control, power good, trim, and output
sense can be readily evaluated. Also the behavior in overload or over-temperature can be evaluated
easily before it is designed in.
The evaluation board also contains the filter components to meet EMC class B levels. Alternate
component positions are included to allow experimentation to optimize the EMC performance depending
on operating conditions and budget.

Notes:
Note1: refer to
Quick Start Guide
1.
Connect P3 to power supply (observe correct polarity!)
2.
Connect P4 to the load (no load operation is allowed. For 0.8Vout, please refer to safe
operating area in the
RPX-1.0
3.
The evaluation module is preset to 5Vout.
The output voltage can be selected with values of 0.8V, 1.8V, 3.3V, 5V, 12V, 15V, and 24V by
shorting a 0W resistor to the respective places as seen in the board silkscreen. For 0.8Vout,
please refer to safe operating area in the
4.
The sense pin is connected to the RPX output pin, so the preset voltage is very accurate at
the output of the RPX. To compensate any losses of the filter, remove the resistor at R2, and
solder a 0W resistor at R3.
5.
CTRL
The device is preset as normally on. It can be disabled by pulling the CTRL pad to GND.
Short R18 to disable the device.
Caution:
ESD sensitive. Always follow ESD preventative procedures when
handling the product!
