PRODUCTION DATA
Figure 8-1 shows a typical application circuit for the LM636x5D-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, see Table 8-1 and
Table 8-2 for typical component values.
