Notes:

3. POK pin must be disconnected from IN pin.

4. Test condition for DFN3030-10: Device mounted on FR-4 2-layer board, 2oz copper, with minimum recommended pad on top layer and 6 vias to

bottom layer 1.0”x1.5” ground plane.

5. Test condition for SOP-8L-EP: Device mounted on 2" x 2" FR-4 substrate PCB, 2oz copper, with minimum recommended pad on top layer and

thermal vias to bottom layer ground plane.
