 Goals

Component selection discussion for the buck converter and current sense circuits

 Discussion topics

Mostafa working on buck + current sense

Rayyan working on MCU + gate driver + power MOSFETs

1. Decide if we need to choose a new buck chip to save layout space

2. Verify Buck Vout yielded by FB resistors work with MCU Vin

3. Consider DC bias effect on MLCC

4. Ask @Farris Matar to check output capacitor calculation because Jerry doesn’t know control system poles and zeros

5. Use Vin_max for calculations to consider the worst cases

6. upload block diagram

7. upload current sense component selection

8. Explain how the RC filter at current sense output works
