• Conducted extensive verification testing and documentation on pre-release 16 – 50V input, 16-60V output DC – DC power converter line.
• Trimmed switching timings to improve efficiency across the line while simultaneously preventing board failures due to tolerance differences.
• Optimized features such as overvoltage turnoff for 20 C, 100 C, and -40 C temperatures, turn-on ramp-up and overshoot, and switching overshoot.
• Inspected and corrected localized board issues which prevented further optimization, such as excessive noise on signal lines.
• Wrote design verification (DV) document cataloging all findings and actions.
• Developed and proposed solutions to failures observed through testing functionalities
