EDN (Electronic Design News) provides engineers and engineering managers with in-depth design features and deep technical information on microprocessors and other digital ICs, analog ICs, ASICs, computers and software, computer peripherals, test and measurement, components, power sources, interconnections and packaging, and much more. EDN also explores important application areas such as computers, communications, embedded, industrial, and consumer electronics.

Designing offline ac/dc switching power supplies, brick by brick
It's a challenge to convert high-voltage ac to dc while keeping efficiency high and cost low.
