Description
LM2596 DC-DC Converter Step-Down Module (Adjustable Buck) – LM2596 / LM2596S / LM2596LED / LM2596HVS
The LM2596 DC-DC Buck Converter Module is a highly efficient, easy-to-use step-down voltage regulator that converts a higher DC voltage into a stable lower DC output. Designed with the popular LM2596 regulator IC, these modules are widely used in Arduino, Raspberry Pi, robotics, LED drivers, battery chargers, and power supply projects.
Available in multiple variants:
-
LM2596 Standard – Adjustable buck converter (input up to 40V).
-
LM2596S – Surface-mount version with compact design.
-
LM2596 LED – Specially designed as an LED driver with constant current capability.
-
LM2596HVS – High-voltage input version (up to 60V).
These modules are cost-effective, reliable, and essential for any electronics toolkit.
