The RPP30 series 2:1 input range DC/DC converters are ideal for high end industrial
applications and COTS Military applications where a very wide operating temperature
range of -40°C to +115°C is required. Although the case size is compact, the conver-
ter contains a built-in filter EN55022 Class B / FCC Level B without the need for any
external components. The RPP30 is available in two case styles: the ribbed case and the
baseplate case for high vibration, bulkhead-mounting or for passive cooling applications.
They are UL-60950-1 certified.

Notes :
1. Typical values at nominal input voltage and no load/full load.
2. Min. values at nominal input voltage and full load.
3. 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. RPP30-2405S, RPP30-4805D-B
Positive logic: 0= OFF, 1 = ON. The converter will be ON if the CTRL is left open.
4. Requires an external 100µF low ESR capacitor to meet EN61000-4-4 and EN61000-4-5
5. Case l: 50% Stress, Temperature at 50°C (Ground Benign).
6. 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. 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.
