Optimize the active-clamp flyback topology for higher efficiencies by reducing the switch-node capacitance and using a secondary resonance circuit.
One benefit to a wireless charging stand is less likelihood that you'll mis-place the mobile device to be charged.
If you don't need isolation in a power supply, say when a phone controls a device, an upside-down buck converter can reduce parts count.
Here's a way to reduce switching errors caused by leakage inductance inconsistencies in a quasi-resonant power converter.
Supercapacitors are not only power sources similar to batteries, they also solve some interesting transient power-outage problems.
These equations give you the basics of DC/DC
In part 2, The Busy Blogger looks at the basic architecture of a DC/DC
In a three-part series, Planet Analog's The Busy Blogger looks at DC-DC converters.
This article discusses the benefits of applying embedded capacitance material (ECM) on PCB versus conventional FR4 dielectric material in terms of pow...
LEDs have helped reduce electricity use, but is it all random?
