Product Description
Reverse input protection, reverse connection cannot be burned .It can be step-up and step-down, and the output voltage can be adjusted freely from 0.5 to 30 V, and the current limit of 0 to 4 A can be adjusted to any type. When the button control output is ON/OFF, you can set the default to ON or OFF. Use the rise and drop chip as the main controller, use external 60V 75A MOS transistor as a switch, dual 60V 5A SS56 shotkey rectification and 60V voltage values are better than the unmatured XL6009 / LM2577 program on the market. The pressure value of the MOS tube and the Schottkey diode must be larger than the sumulation of input voltage and input voltage. Low output ripple and LC filter When using heatsinks, the transmitter module supports the isolation column.
