LM2577 3A Adjustable DC-DC Step-Up Boost Converter with LED Voltmeter, 3-34V to 4-35V
The LM2577 3A DC-DC Step-Up Boost Converter Module is an adjustable boost converter designed to increase a lower DC input voltage to a higher output voltage. It supports an input range of 3V to 34V and provides an adjustable output from 4V to 35V, making it suitable for a variety of electronics, DIY, and power supply projects.
The built-in LED voltmeter allows you to monitor the output voltage easily, while its 150 kHz PWM switching operation helps provide stable and efficient voltage conversion. With minimal external components required, this LM2577 module offers a practical and economical solution for applications that need adjustable DC voltage boosting.
Features:
- Multiple output regulators.
- One button switches between input and output voltage displays.
- Power-down memory function.
- To turn off/on the LED display, press the button for 3 seconds.
- With a wire termination.
- When you adjust the blue potentiometer, please use a multimeter to monitor the voltage.
- Rotating clockwise can enhance the voltage, but rotating counterclockwise can lower it.
- When the module's output voltage cannot be changed (the output voltage is always equal to the input voltage) Please adjust the potentiometer counter clockwise for 20 laps (20 turns) or more until it works.
