TYPICAL APPLICATION

Figure 2. Quad 3A (4A Peak) Output from 8.5V to 40V Input

* The output current capability (transient peak or

continuous) in Figure 2 is subject to environmental

factors such as ambient temperature, airflow, or other

cooling techniques. For different VIN, VOUT,

and TA conditions, see the notes section (Note 3) of the

Electrical Characteristics table and the derating curves

in the Applications Information section.
