Notes to Specifications
1.
2.
Above +125°C case temperature, derate output power linearly to 0 at 135°C case.
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load.
See typical waveforms.
3.
4.
5.
Turn-on delay time measurement is for either an application of power at the input or a signal at the shutdown pin.
For operation at 16VDC, derate output power by 33%.
An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the short circuit
protection and is the condition of maximum power dissipation.
