LM2596HVS DC-DC buck converter module
LM2596HVS DC-DC buck converter module—high-voltage step-down regulator up to 3A for industrial, automotive, and DIY electronics.
The LM2596HVS DC-DC Buck Converter Module is a high-voltage, high-efficiency step-down (buck) voltage regulator designed to convert a wide range of DC input voltages into a stable, adjustable lower DC output. Based on the LM2596HVS IC, it supports higher input voltages than standard LM2596 modules, making it ideal for industrial and automotive applications.
This module typically supports input voltages up to 60V (model dependent) and provides an adjustable output voltage via an onboard potentiometer, with output current up to 3A (with proper heat dissipation). It is widely used in Arduino, ESP32, CNC controllers, motor drivers, LED lighting, battery chargers, and DIY power supplies.
Featuring high efficiency, thermal shutdown, and short-circuit protection, the LM2596HVS module ensures reliable and safe power conversion in demanding environments.
