Review & Verify Medical Device Power Supply Schematic Before PCB Layout

Job ID: 40554241

Budget: $10 – $30 USD

I need an experienced Power Electronics / Hardware Design Engineer to review and verify my medical device power supply schematic before PCB layout.

This is not a design project. The schematic is already completed. I need an expert to review the design, identify any issues, and recommend improvements before PCB layout.

The schematic includes:

12V DC Input
12V to 5V / 3A Buck Converter
5V to 3.3V LDO Regulator
Reverse Polarity Protection
Input Fuse
TVS Protection
Common Mode Choke (CMC)
Ferrite Beads
ESD Protection
EMI Input & Output Filters
Scope of Work
Review the complete schematic
Verify component values and selection
Review buck converter and LDO design
Review fuse, TVS, ESD and reverse polarity protection
Review EMI/EMC filtering
Identify design mistakes or reliability concerns
Suggest improvements before PCB layout
Provide PCB layout recommendations for better EMI/EMC performance
