  • @Jerry Tian

  • @Mostafa Hussein

  • @Rayyan Mahmood

  • @Taim Al-Dabbagh

 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
