inner layers are 1 oz. (35µm), while the outer layers are 2 oz. (70µm). A typical curve of maximum load current

versus ambient temperature, for both the LM53603-Q1 and LM53602-Q1, is shown in Figure 18. This data was

remembered that the data shown in these graphs are for illustration only and the actual performance in any given

application will depend on all of the factors mentioned above.
