AC and DC power differ in direction, usage, and efficiency. Learn the basics of how alternating and direct current work and where each is used.

A power tip that discusses how to address highly integrated USB PD charger design constraints with a self-biasing circuit.

And, if this is your first introduction to switched-mode power supplies, check out this in-depth look at the similar buck converter circuit to better understand what’s going on behind the scenes ...

Convert Power RV batteries use direct current power (DC), but most appliances use alternating current (AC). Before you use an RV battery to power the appliances in an RV, you need to convert the DC ...

Sponsored by: Texas Instruments In power-supply POL designs, the power module seems to be gaining favor over a discrete approach when it comes to dc-dc conversion.

That means each device needs to convert AC power to DC, as well as reducing the voltage to the much lower levels used in digital circuits.

Wondering if phone chargers use AC or DC power? Learn the difference, how chargers work, and why it matters for your device’s safety.
