Dickson Charge Pump
Beau shows us the potential current efficiency with a Dickson charge pump. Setup: AC coming into a switch mode power supply riding 12v Dickson Charge Pump Standard Scooter Motor In the video you will see Beau take the enable line and apply it...
That’s what friends are for.
This diptrace schematic is a minimal circuit using the TPS62056DGS voltage regulator. It also depicts a momentary pushbutton switch as a holdover from the previous revision. Beau Schwabe, IC layout engineer and member of our local Ohm Space, revised a circuit he...
A uA saved is really hard earned…
Today I populated another regulator PCB, leaving out the components that won't be in the final design. The standby current at 6v input level is now only 1uA! My latest estimate of the quiescent current of the toggling/control system is ~50uA. I'll refine my numbers as...
The Pan Tilt Zoom Story
Several years ago, I started a live video stream of our church services over at Sherwood Baptist Church here in Oklahoma City. The problem I quickly encountered was that we didn't have enough space in our auditorium to have multiple manned cameras. Thus began the...
Prototype circuit for toggling
Here is the toggling circuit I am working on as represented in the iCircuit iOS simulator. Here I have my 3.3v switching regulator (TPS62056DGS) represented by an op amp with a reference voltage at 1.3v. I am representing an input pin of a 3.3v microcontroller with...
Power under control.
Have you ever finished breadboarding a project and upon reviewing your work observed that a large portion of your breadboard space was being wasted by your voltage regulation system?Have you ever wanted to use switching regulation in a high efficiency low power...
The beginning of a blog…
Most things have a beginning. Well, if one considers the vast expanse of the nonexistent, assuming it does not exist in some alternate dimension, there are many things that never had a beginning. But, this all hinges on the definition of "thing" which may well...
