24V to 5V @ 5A Buck Converter
Adjusted layout for better appearance
PDN analysis:
Encountered some issues, finally calculate the impedance by voltage drop over the current
The screenshots are updated in the design document
12s Pre-charge Circuit
Defined system block diagram
Researched about what pre-charge circuit, CAN interface, and current/voltage sense
Looked at options for pre-charge IC, currently reading the TPS48111 IC
Week 8
Buck:
Components and layout reviewed
Added bottom layer silkscreen and exported the Gerber file for fab
Verified selected Pixhawk connector’s compatibility with the harness
LED Board harness (helped work session)
Board review (6s to 5V buck)
12S Pre-charge
Looked at the TPS chip thoroughly for understanding how it work
Looking for more options for the pre-charge ic
Implement the STM32 MCU and the CAN circuit for the CAN adapter board
Week 9
24V to 5V Buck:
Added bottom layer meme
Export Gerber files and have it verified
Add to order in JLCPCB (midterm order)
12S Pre-charge:
Selected pre-charge IC (TPS48111 chip)
Implemented symbols and footprints
High level system architecture defined
Started looking at options for powering the STM32 (12S to BUCK to LDO to 3.3V)
