Description

U1: RPL-3.0 power module.

C1,C2,L1,L2,L3,L4,C3,C4,C5,C6: allow placement of various sized components to test input filter design. The populated filter is designed to

meet EN55022 class A. Note: Connect a 220uF across the input for damping the LISN.

C7,C8,C9,C10,L5,L6,L7,C11: allow placement of various sized components to test output filter design. The populated filter is designed to meet

EN55022 class A. Note: Connect a 220uF across the input for damping the LISN.

R2 and R5: configure CTRL. R2 is populated to enable the RPL-3.0. Short R5 in order to disable the RPL-3.0.

R1: populated zero ohm resistor for direct output voltage measurement. If sense is desired at a different location, for example after the filter or

directly at the load, unsolder R1, and connect sense to the new measurement point.

R3: sense point for output voltage after the filter. To set sense point here, remove R1 and solder a zero ohm resistor at R3.

VOUT Selection: the output voltage can be selected with values of 1.8V, 3.3V, and 5V by shorting a zero ohm resistor to the respective places

as seen in the board silkscreen.

R16, R17: trim the output voltage. Refer to “OUTPUT VOLTAGE TRIMMING”
