Auto start voltage will be pulled down to 7V less or smaller engine at high speed when the voltage up to 15V or higher. For 12V electrical work hard at work, this automatic buck module solves this problem , regardless of the input voltage is 5V or 12V or 32V, the output can be stabilized at 12V.
Wide Output Voltage 1.25V – 35V ( with automatic buck , scope of work, any voltage inputs can be arbitrarily regulated voltage output ) ;
Built- 4Aefficient MOSFET switches enable efficiency up to 94%; (LM2577 current is 3A)
high switching frequency of 400KHz, the ripple is smaller and smaller . (LM2577 frequency only 50KHz)
