8.2 Typical Application
Figure 8-1 shows a typical application circuit for the LMR33620-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. When using the fixed output voltage version, connect the FB input directly to VOUT. 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.
