dently from the average output voltage. The precision in setting the overvoltage threshold is 7% of the ov-
ervoltage value (for instance V = 60V ± 4.2V).
3.1 Disable function
The zero current detector (ZCD) pin can be used for device disabling as well. By grounding the ZCD volt-
age the device is disabled reducing the supply current consumption at 1.4mA typical (@ 14.5V supply volt-
age).
Releasing the ZCD pin the internal start-up timer will restart the device.
