Note:

When the output voltage is trimmed up, the output power from the converter must not exceed its maximum rating. This is

determined by measuring the voltage on the output pins, and multiplying it by the output current.

The derating curves below give an indication of the output power achievable with and without forced-air cooling. However in the

final application, in order to ensure the reliability of the unit, care must be taken to ensure the maximum case temperature is not

exceeded under any conditions.

The trim feature allows the user for adjusting the output voltage by means of an external resistor. To increase Vo resistor

should be connected between pins 12 and 14. To decrease Vo a resistor should be connected between pins 12 and 13.

To increase Vo:
