Notes:

1. C6 = 2 X 180ÂµF in parallel.

2. Suitable for typical notebook computer application of 4A continuous, 6A peak for VDDQ. If continuous operation

above 6A is required, use single SO-8 packages. For more information, refer to the Power MOSFET Selection

Section and use AN-6002 for design calculations.
