How to Select Inductor for Boost Converter

1. Select Inductance Value a. Define the switching frequency for the boost converter Example: Fsw = 300kHz b. Define the input and output voltage Example: Vin = 12V, Vout = 24V c. Determine the duty cycle Dutycycle = 1 – (Vin / Vout) Example: Dutycycle = 1 – (Vin / Vout) = 1 – (12V / 24V) = 50% d.
