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 rated resistive load at 25C ambient unless otherwise specified.
