PRODUCTION DATA
Figure 8-1 shows a typical application circuit for the LMR38015. This device is designed to function over a wide range of external components and system parameters. However, the internal compensation is designed for a certain range of external inductance and output capacitance. As a quick-start guide, Table 8-1 provides typical component values for a range of the most common output voltages.
