Description

The RPP20 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 very compact, the

converter contains a built-in filter EN55022 Class B / FCC Level B without the need for

any external components. The RPP20 is available in two case styles: the ribbed case for

active cooling and the baseplate case for high vibration, bulkhead-mounting or for pas-

sive cooling applications. They are UL-60950-1 certified.

ICE (Innovation in Converter Excellence)

uses state-of-the-art techniques to mini-

mise internal power dissipation and to

increase the internal temperature limits

to extend the ambient operating

temperature range to the maximum.

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. RPP20-2405S, RPP20-4805D-B.

Pos. 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 bottom plate is pressed firmly into place into the aluminium case.The hydraulic press can leave

tooling marks and deformations to both the case and plate. 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.

7. Example:

thcase-ambient = 7.5°C/W (vertical) Tcase = Case Temperature

thcase-ambient = 11.5°C/W (horizontal) Tambient = Environment Temperature

dissipation = Internal losses

thcase-ambient =

Tcase - Tambient
