This file type includes high-resolution graphics and schematics when applicable. A common project requirement is to have an adjustable voltage regulator programmed to deliver a specific dc output.

I made this Arduino project that allows to turn ON and OFF LEDs using a cheap IR remote control as a preparation for the next big step: disassemble my girlfriend’s chinese LED lamp and replace its ...

This design uses I2C control to adjust a regulator’s output voltage plus or minus 127 steps in 5 mV increments. Using an I2C-controlled DAC (IC2) to inject current into the feedback node of a stepdown ...
