¹U_{i min}will not be as stated if U_ois increased above U_{o nom}by use of the R input pin. If the output voltage is set to a higher value, U_{i min}

will be proportionally increased.

²Measured with a resistive or max. admissible capacitive load. (See fig.: Converter start-up and rise time).

³Measured with a lead lenght of 0.1 m, leads twisted. Double output units with both outputs in parallel.

⁴Source impedance according to prETS 300132-2, version 4.3.

⁵The level of the switching frequency band varies with the output voltage configuration. (See also fig.: Switching frequency versus

input voltage and load.)
