Boost Converter Component Selection Template

Coverage:

1. Duty cycle of the converter (ideal or non-ideal)

2. Value of the inductance needed

3. The boundary between CCM and DCM (Imin in the wave form)

4. Peak current of the diode, MOSFET and the inductor

5. RMS and DC current of the diode

6. RMS and DC current of the MOSFET

7. Maximum voltage seen by the diode

8. Maximum voltage seen by the MOSFET

9. RMS and DC current of the inductor

Under part 5 “Component Selection” section, the following suggestions are provided:

1. The right MOSFET voltage rating for the design

2. The right MOSFET DC or RMS current for the design

3. The maximum current rating a MOSFET must have to match the design

4. It advises the right diode current rating (DC, RMS, Peak)

5. It advises the right diode voltage rating (PIV)

6. It advises the proper or the right core material to use

7. It advises the minimum number of turns for the inductor to prevent saturation

8. It advises the right size of the wire to use in the inductor

9. It will also advises the value of the output capacitance and its voltage rating
