3 Configuring the Boost Converter

This section describes the basic steps for configuring the boost converter. See the following sections for more details.

1. Select the boost voltage.
   Based on the rated voltage of the load, set the feedback resistors to the appropriate boost voltage (Section 4).
2. Calculate the load current.
   Estimate the maximum required load current to support the voltage, capacitance, and frequency of the load (Section 5).
3. Select an inductor.
   Choose an inductor with an inductance value between 3.3 µH and 22 µH, and a saturation current rating more than 1 A (Section 6).
4. Set the current limit and R_EXT resistor.
   Calculate the R_EXT resistor based on the saturation current of the inductor (Section 6.4).
5. Compare the maximum boost current.
   Compare the maximum boost current with the required load current calculated in step 2 (Section 7).
6. Choose an input and output capacitor.
   Input and output capacitors help reduce the effects of ripple and transient load currents on the supply and output voltages (Section 8).
7. Verify performance.
   Verify the performance of the components selected.
