This design was conceived as an add-on for the Variable DC Power Supply, a very successful circuit posted to this website. This simple unit provides a dual-rail variable output ranging from ±2.5V to ...

This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

For an upcoming road trip, [Patrick] needed a small variable power supply. Instead of lugging around a bench supply, [Patrick] did the sensible thing and reverse engineered a cell phone charger to fit ...

Modern integrated circuits are increasingly vulnerable to power supply noise and the ensuing induced jitter, phenomena that can significantly impair circuit reliability and performance. The interplay ...

Advanced power packages are breaking barriers that affect dc, ac and thermal performance in switch-mode power supply circuits for a broad range of applications. Lily Hsiu-shih Chu, Evaluation Engineer ...

Learn how to select a power-supply configuration based on PPG system requirements. Review the implementation of switched-mode power-supply reference circuits for both discrete (part one) and ...
