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. RPP30-2405SW, RPP30-4805DW-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.

7. Example:

Rthcase-ambient = 7.3°C/W (vertical)

Tcase = Case Temperature

Rthcase-ambient = 11°C/W (horizontal)

Tambient = Environment Temperature

Pdissipation = Internal losses

Rthcase-ambient =

Tcase - Tambient

Pin = Input Power

Pdissipation

Pout = Output Power

Pdissipation = Pin-Pout =

Pout

- Pout

Ƞ = Efficiency under given Operating Conditions

Rthcase-ambient = Thermal Impedance

Pdissipation = Pin-Pout =

Pout

- Pout

Practical Example:

Take the RPP30-2405SW with 90% load. What is the maximum ambient operating temperature? Use converter vertical in application.

Effmin = 89% @ Vnom

Pout = 30W

Poutapp = 30 x 0.9 = 27W

Pdissipation =

Pout

- Pout

Rth =

Tcasemax - Tambient

--> 7.3°C/W =

115°C - Tambient

Pdissipation

3.34W

Ƞ = ~89% (from Eff vs Load Graph)

ambient = 90.64°C

Pdissipation =

- 27 = 3.34W

0.89
