Summary of 0-30V REGULATED DIGITAL SWITCHING POWER SUPPLY ATMEGA8 LM2576ADJ
This article describes a high-quality 0-30V regulated digital switching power supply using an ATmega8 microcontroller and LM2576ADJ. It features a 2×16 LCD display for voltage and current monitoring, with a maximum output current of 0.3A. The design includes source code hex files and PCB drawings in MDI format, which can be converted to BMP for viewing. The circuit operates from a 12V DC input and utilizes an LM324 op-amp powered by a symmetric ±9V regulated supply derived from an LMC7660 or transformer.
Parts used in the Digital Switching Power Supply:
- ATmega8 microcontroller
- LM2576ADJ adjustable switching regulator
- 2×16 LCD display
- LM324 op-amp
- LMC7660 voltage converter
- Symmetric +/-9V regulated circuit
- 9V transformer
- PCB files (MDI/BMP format)
- Source code hex file
