Analog Meets Digital Part 5: Power Supplies

Designing analog electronics hardware is less orderly and predictable than digital electronics design. In Part 5 of this series, Andrew focuses on one of the least glamorous but most critical components of electronic circuits—their power supplies. He presents real-world examples, tips, and pitfalls of mains power, offline linear and switching supplies, USB power delivery, and disposable and rechargeable lithium batteries.
