8.2.4 Boost Converter
The recommended application for the boost converter is given in Figure 39. For the best performance, a Schottky
diode and a 22 µH coil is required. The current limit for the internal FET (and the maximum current in the coil)
can be adjusted and in the recommended application it is set to 0.1 V/0.33 Ω = 300 mA.
