V i min will not be as stated, if V o is increased above V o nom by use of the R or Trim input. If the output voltage is set to a higher value, V i min
will be proportionally increased.
Measured with a resistive and the max. admissible capacitive load.
Measured with a lead length of 0.1 m, leads twisted. Double-output models with both outputs in parallel. 70/110 IMX7 models need an
external capacitor at the input, e.g., 1 μ F film or ceramic.
Source impedance according to ETS 300132-2, version 4.3, at V i nom .
The DC-DC converter shuts down automatically at approx. 38 V.
Operation at lower input voltage possible: P o approx. 80% of P o nom at V i min = 14.4 V.
