NOTES:
1.Maximum package power dissipation limits must be observed.
2.Low duty cycle pulse techniques are used during test to maintain junction temperature as close to ambient as possible.
3.VID1, VID3, VID4 = logic 0, and VID0, VID2 = logic 1.
4.Vsense is provided from a low impedance voltage source or shorted to the output voltage.
5.Under a typical soft current limit, the net soft–start discharge current will be 90

sink to source current ratio is designed to be 9:1.
6 Sense (Pin 6) = 5.0 V, Comp (Pin 10) open, VID4, VID2, VID1, VID0 = 1.0, VID3 = 0.
7.OUTEN is internally pulled low if VID0, 1, 2, 3, and 4 are floating.
8.Due to internal pull–up resistors, there will be an additional 0.5 mA per pin if any of the VID0, 1, 2, 3, or 4 pins are pulled low.
