LM2596S DC-DC Step-Down Buck Converter Module

The LM2596S with SMD LED is a highly efficient DC-DC step-down (buck) switching regulator module. Based on the Texas Instruments LM2596 IC, it delivers stable adjustable output voltage from 1.5V to 35V with a rated current of 2A (maximum 3A) and up to 92% conversion efficiency — far superior to linear regulators like the 7805.

Key Features

• Input Voltage: 3V – 40V DC
• Output Voltage: 1.5V – 35V DC (Adjustable via onboard potentiometer)
• Output Current: Rated 2A, Maximum 3A (heatsink required above 2.5A)
• Switching Frequency: 150 kHz — allows smaller filter components
• Conversion Efficiency: Up to 92%
• Operating Temperature: -40°C to +85°C (Industrial grade)
• SMD LED Indicator: Power-on status indicator
