The RPP30-W series 4:1 input range DC/DC converters are ideal for high end industrial
applications and COTS Military applications where a very wide operating temperature
range of -45°C to +120°C is required. The converters are also optionally available with a
-55°C start-up temperature. Although the case size is compact, the converter contains a
built-in filter EN55022 Class B / FCC Level B without the need for any external components.
The RPP30-W is available in three case styles: the high operating temperature ribbed case,
the low profile flat case and the baseplate case for high vibration or bulkhead-mounting
applications. They are UL-60950-1 certified.

Notes :
1. Typical values at nominal input voltage and no load/full load.
2. 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 pin voltage is referenced to negative input. The pin is pulled high internally.
ON/OFF control is standard with positive logic: e.g. RPP30-2405SW, RPP30-4805DW-B.
Add “1” before the suffix for negative logic: e.g. RPP30-2405SW-1, RPP30-4805DW-1B.
Positive logic: 0= OFF, 1 = ON. The converter will be ON if the CTRL is left open.
Negative logic: 1 = OFF, 0 = ON. The converter will be OFF if the CTRL is left open.
5. Requires an external 100µF 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.

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 MLCC
To ensure optimum thermal performance, use large areas of copper on the PCB to assist with heat dissipation and mount the converter vertically.
