LM2596S DC-DC Step-Down Power Supply with SMD LED Indicator

The LM2596 HV DC-DC Buck Converter is a high-voltage, efficient step-down (buck) voltage regulator module that can convert a wide input voltage range (4.5V to 40V) down to a lower adjustable output voltage (3V to 35V). This module is ideal for applications requiring stable and adjustable power supply voltages with high efficiency and low power consumption.
