Description
The LM2577 3A DC-DC Step UP LED Voltmeter 3-34 to 4-35V Adjustable Boost Converter module is a 150 KHz fixed frequency PWM buck (step-down) DC/DC module. Requiring a minimum number of external components, these regulators are cost-effective, and simple to use.
This version of LM2577 DC-DC step-up (boost) power supply module includes the very useful addition of an integrated digital voltage meter.
Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 3 – 34V and an adjustable output range of 4 – 35V.
