Microcontroller Based DC-DC Converters



Collection of Instructables with microcontroller based step-down, buck-boost, and boost converters. The converters are constant current, constant voltage, or both. Their applications include: DIY DC power supply, LED drivers, battery chargers, and electrolysis.

In microcontroller based DC-DC converters, the programmed chip reads the output current or voltage and generates a PWM output to drive the switch rather than using a dedicated chip to do the job.

Compared to using dedicated IC's, the adva…
