Input Specifications (Conditions are at 48 Vin, full load, and 25°C ambient unless otherwise specified)
Note: Stresses in excess of the maximum ratings can cause permanent damage to the device. Operation of the device is not implied at these or any other conditions
in excess of those given in the specification. Exposure to absolute maximum ratings can adversely affect device reliability.
