Buck Boost Converter

LCD input and output voltage, output current output power; Input anti-reverse protection, reverse connection will not burn. It can be step-up and step-down, the output voltage 0.5-30V arbitrary regulation, limiting the current 0-4A arbitrary regulation. Output anti-intrusion, the battery charge without additional anti-reflux diodes, Button control output ON / OFF status, and you can set the power-on default is ON or OFF. Ascending and descending chip used as the main controller, external 60V 75A MOS tube as a switch, double 60V 5A SS56 Schottky rectification, 60V voltage value, superior to the market immature XL6009 / LM2577 program (a lot Device pressure value is not enough, MOS tube and Schottky diode pressure value must be greater than the input plus input voltage value); Output ripple small, LC filter;
