Description of 4A Buck-Boost Converter Module Adjustable Buck-Boost Board With LCD Display 

Buck-Boost Converter is discussed here. The connection of LCD input and output voltage, output current, output power, input anti-reverse protection, reverse connection will not burn. This module could be step-up and step-down also. The output voltages are arbitrary regulation and its range is 0.5-30V.  The current arbitrary regulation value is 0-4A. the battery will charge without any anti-reflux diodes. It also has the On/OFF status button. We can set the button as power-on default is On or Off. Here we use ascending and descending chip as the main controller. We use an external 60V 75A MOS tube. We use this tube as a switch. This module has the double 60V 5A SS56 Schottky rectification. Its voltage value is 60V. The device pressure value is not sufficient but MOS tube and Schottky diode pressure value must be greater than input and input voltage.  Its output ripple value is so small. And it also has an LC filter. Buck COnverter is available at epro.pk.

Product Description of Buck-Boost Converter Module:

It has LCD input and output voltage, output current output power

The reverse connection input anti-reverse protection will not burn.

It could be step-up and step-down. The arbitrary regulation of voltage and current is output voltage is about 0.5-30 V and the current value is 0-4A.

The battery will charge without additional anti-reflux diodes.

Users can set the button default as ON or OFF. It also has button control output ON/OFF.

Its output ripple value is small and it also has an LC filter.

It also contains a heat sink.
