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...

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...

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...

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...
