1) Typical maximum current capability is given in Figure 13. The external components are in accordance with the
application information (refer to Chapter 15).
2) Not subject to production test; specified by design.
3) Values verified in characterization with boost converter specified in Chapter 15.1. Not subject to production test;
specified by design. Refer to Figure 14 for additional information.
4) Calculated value based on other measurements.
