DC vs. AC Voltage: DC voltage is constant and zero frequency, while AC voltage alternates polarity and has a frequency, typically 50Hz or 60Hz. Reducing DC Voltage: Diodes and resistors can reduce DC voltage, with diodes creating a voltage drop and resistors forming a voltage divider circuit. ...
A SIMPLE explanation of DC Current. Learn what DC Current is, the symbol for DC Current, and the difference between AC and DC current. We also discuss how to measure DC Current, and who invented DC Current.
A DC voltage is a voltage that produces, or would produce, DC current, and an AC voltage produces or would produce AC current—and this introduces another terminology problem. “DC” and “AC” are sometimes attached to the word “current,” even though these...

external compensation allow the transient response to be optimized over a wide range of loads and output capacitors. Cycle-by-cycle current limit provides protection against shorted outputs and soft-start eliminates input current surge during start-up. The RT8290A also provides output under voltage ...
