Notes:
1. Range of Vin can be up to 30V, but R1 and R2 must be scaled such that VGS of Q2 does not exceed 20V.
2. R
θ
JA is the sum of the junction-to-case and case-to-ambient thermal resistance where the case thermal reference is defined as the solder mounting
surface of the drain pins. R
θ
JC is guaranteed by design while R
θ
JA is determined by the user’s board design.
3. Pulse Test: Pulse Width < 300μs, Duty Cycle < 2.0%.
FDC6330L Load Switch Application
External Component Recommendation:
For applications where Co
1
μ
F.
For slew rate control, select R2 in the range of 1k - 4.7k
.
For additional in-rush current control,C1
1000pF can be added.
Select R1 so that the R1/R2 ratio ranges from 10 - 100. R1 is required to turn Q2 off.
