8.2 Typical Application
Figure 13 shows a typical application circuit for the LMR36510. 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, provides typical component values for a range of the most common output voltages.
