1.
2.
See typical waveforms.
3.
Turn-on delay time measurement is for either an application of power at the input or a signal at the shutdown pin.
4.
For operation at 16VDC, derate output power by 33%.
5.
Above +85
°
C case temperature, derate maximum input voltage linearly to 33V at +125
°
C case.
Above +105
°
C case temperature, derate output power linearly to 0 at 125
°
C case.
Recovery time is measured from the initiation of the transient to where V
