ZHCSIN6C August 2018 – October 2019 LMR36015-Q1
PRODUCTION DATA.
Figure 18 and Figure 19 show typical application circuits for the LMR36015-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, Table 3 provides typical component values for a range of the most common output voltages.
