San Jose, CA

• Key Responsibilities:
• New product design verification, troubleshooting and introduction.
• Semiconductor fab facility evaluations and process transfer evaluations.
• Regulatory agency pre-approval testing for EMC (Conducted and Radiated Emissions), line transient immunity, efficiency, leakage current and acoustics.
• Design and managed automated test platforms (Test hardware, fixtures, harnesses, data collection and analysis) for many power supplies including battery chargers, LED drivers, PFC products and resonant converters.
• Directly supported customers, sales, marketing and field application engineers with design, testing and failure analysis.Notable Projects:

Santa Rosa, CA

• Assisted in the design, testing and certification of extremely low-noise multiple-output power supplies ranging from 100W to 850W.
• Scope of work included design validation at the schematic, PCB layout, thermal, electrical, mechanical and level.
• Performed evaluations and validation of EMC compliance (conducted/radiated emissions), power line transient immunity, leakage current and acoustic performance.
• Quickly addressed production, manufacturing and quality related problems.
• Supported internal engineering groups to solve power supply end-use related problems.
• Quickly identified the source of a power supply defect that was causing $1.5M per day in lost sales due to manufacturing production line stoppages.
