Description

Caution:

ESD sensitive. Always follow ESD preventative procedures when

handling the product!

Quick Start Guide

1. Connect P3 to power supply (observe correct polarity!)

2. Connect P4 to the load (no load operation is allowed)

3. The evaluation module is preset to 5Vout.

The output voltage can be selected with values of 1.8V, 3.3V, and 5V by shorting a 0

W

resistor to the respective places as seen in the board silkscreen.

4. The sense pin is connected to the RPL output pin, so the preset voltage is very accurate at

the output of the RPL. To compensate any losses of the filter, remove the resistor at R1, and

solder a zero ohm resistor at R3.

5. CTRL

The device is preset as normally on. It can be disabled by pulling the CTRL pad to GND.

Short R5 to disable the device.

Notes:

Note1: refer to SAFE OPERATING AREA of RPL-3.0 datasheet

The RPL-3.0-EVM-1 generates a constant output voltage selectable from 1.8V, 3.3V, or 5V from a DC

input in the range of 4 – 18V. It has a maximum continuous output current of 3 A.

All the functions of the RPL-3.0 such as output voltage selection, control, power good, 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 A levels. Alternate com-

ponent positions are included to allow experimentation to optimize the EMC performance depending on

operating conditions and budget.
