Note:
Performance
Regulation for the VIPer22A-E and VIPer12A-E can be seen below. Keep in mind that the
buck topology will peak charge at zero load. DZ1 will clamp the voltage to 3 - 4 V above the
output. Load regulation is taken from 0.03 A to 0.35 A.
The following measurements were taken on the appropriate version of the boards.
Discrepancy of measurements can be present, which is to be expected due to the 5%
tolerance of the Zener and equipment used for the measurements. The measurements
shown are at room temperature. If higher operating temperatures are used, current loads
must be adjusted accordingly.
