FAN5026
Notes:
1. Suitable for applications of 4A continuous, 6A peak for VDDQ. If continuous operation above 6A is required use single SO-8
packages for Q1A (FDS6612A) and Q1B (FDS6690S) respectively. Using FDS6690S, change R7 to 1200Ω. Refer to Power
MOSFET Selection, page 14 for more information.
2. C6 = 2 X 180µF in parallel.
