Скачать или смотреть LM2596 Buck Converter Circuit: Adjustable Step-Down Regulator | Design in Altium Designer

In this tutorial, I’ll design an LM2596-based buck converter circuit that steps down input voltage (e.g., 12V → 5V) with adjustable output using a 100K potentiometer (VR1). The circuit uses a 33μH inductor (L1), SS34 diode (D1), and 220μF output capacitor (C2) for stable voltage regulation – no microcontroller needed. Ideal for battery-powered projects, solar systems, or power supply customization.

✅ What You’ll Learn:

Schematic Design: How the LM2596ADJ IC configures for adjustable step-down conversion.
PCB Layout in Altium Designer 24.4.1: Component placement for thermal management and EMI reduction.
Component Selection: Choosing the right inductor, diode, and capacitors for stable output.
