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.

All specifications are typical at nominal input Vin = 48V, full load under any resistive load combination at 25ºC unless otherwise stated.
