Evaluation platform for RPM-6.0 Features buck regulator modules Evaluation Module Thermal design considerations included EMI Class B filter Evaluation Easy evaluation of trimming, sequencing, soft start, Module enable and sensing functions RPM-6.0-EVM-1 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. Selection Guide Part Input Output Output Number Voltage Range Voltage Current VDC VDC A RPM3.3-6.0-EVM-1 4 - 15 3.3 6 RPM5.0-6.0-EVM-1 4 - 15 5 6 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 0 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. www.recom-power.com REV.: 3/2020 P-1RPM-6.0-EVM-1 Evaluation Module Specifications (measured Ta= 25C, full load after warm up unless otherwise stated) Component Placement RECOM 12.2x12.2mm Evaluation Board version 03 L1 L7 L2 C7 L4 C8 L8 L5 L3 VIN VOUT IC1 1 1 2 2 L6 3 3 SENSE 4 4 5 5 GND GND C9 R8 R2 R1 R7 CON3 CON4 ON EN OFF PG SEQ MODE VSEL Connector Description Con1 Con2 Pin Name Description Pin Name Description 1,2 V Positive Input Voltage (observe correct polarity ) 1,2 V Positive Output Voltage in out 3 NC Not connected 3 SENSE Output Voltage Sense Pin (leave open if not used) 4,5 GND Negative Input Voltage (Common GND) 4,5 GND Negative Output Voltage (Common GND) Con3 Con4 Pin Name Description Pin Name Description 1 ON Connect to Vin 1 PG Power Good Signal 2 EN Enable Pin (leae open if not used) 2 SEQ Sequencing and soft start 3 OFF Connected to GND 3 MODE Not used 4 VSEL Not used www.recom-power.com REV.: 3/2020 P-2 CON1 C1 C2 C5 C6 R3 R6 R5 C3 C4 R4 CON2
