Module

• Evaluation platform for RPM-1.0

buck regulator modules

• Thermal design considerations included

• EMI Class B ﬁlter

• Easy evaluation of trimming, sequencing, soft start,

enable and sensing functions

Description

The RPM3.3-1.0-EVM-1 and RPM5.0-1.0-EVM-1 generate a constant output voltage with an

output current up to 1A from an external DC Source. All the functions of the RPM3.3-1.0 and

RPM5.0-1.0 like trimming, sequencing, soft-start, enable and sensing can be evaluated. Also the

behavior in overload or over temperature can be evaluated easily before it is designed in. There are also

evaluation modules with other output currents available.

RPM3.3-1.0-EVM-1 3 - 17 3.3 1

RPM5.0-1.0-EVM-1 3 - 17 5 1

Caution:

ESD sensitive. Always follow ESD preventative procedures when

handling the product!

Quick Start Guide

1) Connect CON1 to power supply

2) Connect CON2 to a Load

3) Connect sense to the required potential

The sense preset is via R3 directly at the power module, so the preset voltage is very accurate

at the output of the RPM. To equalize ohmic losses of the ﬁlter, remove the resistor at R3, and

solder a 0Ω resistor at R4. To sense directly at the load, desolder R3 and R4, and connect

Pin3 of CON2 to the positive potential of the load.

Notice: if voltage drop from the output to the load is too high, voltage overshoots may occur

– especially during load jumps.

4) Disable the device via CON3

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

Short R1 to disable the device.

RPM-1.0-EVM-1 Evaluation Module Specifications (measured @ Ta= 25°C, full load after warm up unless otherwise stated) OUTPUT VOLTAGE TRIMMING The RPM series offers the feature of trimming the output voltage over a range between 0.9V and 6V by using external trim resistors. The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.
