Typical values at nominal input voltage and full load. 3. Typical values at nominal input voltage and full load in vertical orientation and with Eurocard-sized PCB ground planes to assist in heat dissipation. For horizontal orientation, reduce the maximum temperatures by 10°C. 4. The ON/OFF control function can be positive or negative logic. The pin voltage is referenced to negative input. Positive logic ON/OFF is standard, no suffix (Ex. RPP50-2405S) Negative logic ON/OFF option has suffix /N (Ex. RPP50-2405S/N) 5. Requires an external 100µF/100V low ESR capacitor to meet EN61000-4-4 and EN61000-4-5 6. Case l: 50% Stress, Temperature at 50°C (Ground Benign). 7. To ensure a good all-round electrical contact, the baseplate is pressed firmly into place within the aluminium housing.The hydraulic press can leave tooling marks and deformations to both the housing and baseplate. The case is anodised aluminium, so there will be natural variations in the case colour and the aluminium is not scratch resistant. Any resultant marks, scratches and colour varations are cosmetic only and do not affect the operation or performance of the converters. RPP40 RPP50 Recommended PCB Layout Single Output Dual Output C2 C1 Fuse C2 C1 Fuse C3 Input Fuse is recommended, but optional. Recommended fuse rating = double maximum input current, time delay type. Input Capacitor, C1, is required to meet EN61000 Surge and Fast Transient, otherwise it is not required for normal operation. Output Capacitors C2/C3 are recommended, but not required for normal operation. Typical capacitor values are 1µF/100V MLCC To ensure optimum thermal performance, use large areas of copper on the PCB to assist with heat dissipation and mount the converter vertically. www.recom-international.com REV:0/2009 PP-19 RPP40/50 Series POWERLINE+ DC/DC-Converter Typical Characteristics RPP50-4805SW RPP40-4805SW Efficiency VS Input Voltage 92 91 90 89 88 87 86 85 84 83 82 Efficiency (%) Efficiency (%) Efficiency VS Input Voltage 36 40 48 52 56 60 Input Voltage (V) 64 68 72 92 91 90 89 88 87 86 85 84 83 82 36 40 48 52 56 60 Input Voltage (V) 64 68 72 Package Style and Pinning (mm) 3rd angle projection 30.5 50.80 RPP40 RPP50 11.70 dia. 1.0 5.1 Stando = 1.3 45.70 3.3 Pin Connections 5.10 10.20 1 3 Bottom View Pin # 1 2 3 4 5 6 10.20 2 4 6 10.20 7.6 Refer to Application Notes for suggested Resistor Values -Vout -Vout Trim Up +Vout REV: 0/2009 10kW Trimpot Trim Trim Down PP-20 Dual +Vin -Vin +Vout Com -Vout CTRL Pin Pitch Tolerance ±0.35 mm 5 External Output Trimming Single +Vin -Vin +Vout -Vout Trim CTRL Trim 10kW Trimpot 10kW Trimpot +Vout www.recom-electronic.com
