Notes: During short circuit, converter will shut down and attempt to restart once per second.
The average current during this condition will be very low and the device can be safely left in this condition
continuously. For specific output voltage specifications, see the corresponding detailed data sheet.
*PCB less than 130°C.
**OVP set to limit maximum voltage in system to a safe level. This can be adjusted for higher voltages if needed.
