The HW‑411 is a compact and efficient DC-DC buck converter based on the LM2596 regulator. It converts higher DC voltages to a stable lower DC output, making it ideal for powering microcontrollers, single-board computers, LED drivers, battery packs, and other electronic modules in DIY and embedded projects.
Features:
Adjustable output voltage down to 1.25 V via onboard potentiometer
High efficiency (up to ~92%) with low heat generation
Capable of delivering up to 3 A continuous output
Input voltage compatibility from 4.5 V to 40 V
Includes onboard indicator LEDs and trim potentiometer
Built-in thermal and overload protection
Compact size with screw terminals for easy wiring
