Design Guide for Creating Reliable Automotive Power Supplies

Power supplies used in automotive applications are subject to harsh conditions in the vehicle. A new application note (AN-106Q) from Power Integrations provides a comprehensive guide to designing a safe, stable, and reliable power supply using AEC-Q100 qualified InnoSwitch3-AQ offline switcher ICs. Design engineers can benefit from step-by-step instructions for component selection, magnetic design and PCB layout, all tailored for the automotive domain.

Download the design guide now and learn about:

• Electromagnetic Interference Immunity: Get layout recommendations for high EMI conditions
• Elevated Ambient Temperature: Ensure consistent performance across a wide temperature range
• Space Constraints: Optimize component placement for compact automotive spaces
• High Reliability Requirements: Discover techniques to enhance the longevity and reliability of your power supplies in demanding automotive conditions

InnoSwitch3-AQ devices combine primary and secondary controllers and safety-rated feedback into a single IC, allowing accurate output voltage regulation even with a wide input voltage range of 30 VDC to greater than 1000 VDC. Operation at 30 VDC enables systems to meet functional safety active discharge requirements.

The InnoSwitch3-AQ family offers 750 V Silicon, 900 V Silicon, 900 V GaN and 1700 V SiC options. These ICs deliver up to 100 W of output with better than 93 percent efficiency and eliminate the need for heat sinks. To learn more,
