Product Description
The LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V Adjustable Boost Converter module is a DC/DC module that uses a 150 KHz fixed frequency PWM to lower the input voltage. These regulators are easy to use and require only a few external components, making them cost-effective.
