Description

The RPM3.3-6.0-EVM-1 and RPM5.0-6.0-EVM-1 generate a constant output voltage with an output current up to 6A from an external DC Source. All the functions of the RPM3.3-6.0 and RPM5.0-6.0 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.

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.

IC1: RPM-6.0 power module. C1,C2,L1,L2,L3,L7,C5,C6: allow placement of various sized components to test input filter design. The populated filter is designed to meet EN55022 class B. C7,C8,L4,L5,L6,L8,C3,C4: allow placement of various sized components to test output filter design. The populated filter is designed to meet EN55022 class B. R1 and R2: configure enable pin. These resistors are not populated. The preset of IC1 is always on. Refer to IC1 datasheet for more information. C9: sets soft-start time. Refer to IC1 datasheet for more information. R3: populated 0Ω 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 R3, and connect sense to the new measurement point. R4: sense point for output voltage after the filter. To set sense point here, remove R3 and solder a 0Ω resistor at R4. R7 and R8: no function on this board. R5 and R6: trim the output voltage between 0.9V and 6.0V

The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary.
