• Evaluation platform for RPMH-0.5 Power Modules

• Thermal design considerations included

• EMI Class B ﬁlter

• Easy evaluation of control, power good and

sensing functions

Description

The RPMH-0.5-EVM-1 generates a constant output voltage with an output current up to 0.5A from an

external DC source. All the functions of the RPMH-0.5 like trimming, sequencing, control, and sensing

can be evaluated. Also the behavior in overload or over temperature can be evaluated easily before it is

designed in.

Caution:

ESD sensitive. Always follow ESD preventative procedures when

handling the product!

Quick Start Guide

1) Connect P1 to power supply (observe correct polarity!)

2) Connect P2 to a Load

3) Connect sense to the required potential

The sense preset is via R1 directly at the power module, so the preset voltage is very accurate at the

output of the RPMH-0.5. To equalize ohmic losses of the output ﬁlter, remove the resistor at R1, and

solder a 0Ω resistor at R2.

4) Disable the device via R5

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

Short R5 to disable the device.
