Notes:
3. Refer to figure 8 for the device derating curve.
4. Test condition for SO-8-EP: Device mounted on FR-4 PCB, 2”x2”, 2oz copper, minimum recommended pad layout on top layer and thermal vias to
bottom layer ground plane. For better thermal performance, larger copper pad for heat-sink is needed.
