LM2577 3A DC Boost LED Display
This module, the LM2577 3A DC Boost LED Display, is designed to be a reliable and affordable solution for regulating voltage. It operates at a 150 KHz fixed frequency and utilizes PWM buck (step-down) technology. With its minimal external components, this module offers convenience and cost-effectiveness in use.
The upgraded LM2577 DC-DC step-up (boost) power supply module now comes equipped with an integrated digital voltage meter, making it even more practical and convenient.
With its accurate multi-turn potentiometer, the module allows for easy adjustment of output voltage within the supplied range, eliminating the need for an external voltage meter. Additionally, it offers a wide operating range with a DC input supply range of 3-34V and adjustable output range of 4-35V.
Included in the package are various features that enhance the overall experience.
- Regulator with multiple outputs.
- Just one button needed to toggle between input and output voltage display.
- Enable the function to power down your memory.
- Holding down the button for 3 seconds will toggle the LED display on or off.
- Equipped with a wiring terminal.
- When making adjustments to the blue potentiometer, please utilize a multimeter to monitor the voltage.
- Rotating in a clockwise direction increases the voltage, whereas rotating counterclockwise decreases it.
- If the LM2577 3A DC Boost LED Display output voltage cannot be changed, adjust the potentiometer counterclockwise for at least 20 laps until it becomes functional.
