8.2 Typical Application
Figure 8-1 shows a typical application circuit for the LMR33630-Q1. This device is designed to function over a wide range of external components and system parameters. However, the internal compensation is optimized for a certain range of external inductance and output capacitance. As a quick start guide, Figure 8-1 provide typical component values for a range of the most common output voltages. The values given in the table are typical. Other values can be used to enhance certain performance criterion as required by the application. Note that for the VQFN package, the input capacitors are split and placed on either side of the package; see Section 8.2.2.6 for more details.
