Adjustable step-up and step-down power supply module constant voltage and constant current solar charging can recover step-up and step-down SJ4 -69994
product detail
The adjustable buck-boost constant-voltage constant-current power supply module adopts an external high-power MOS, and a large package high-current high-voltage Schottky diode to increase heat dissipation and copper deposition. The performance is better than the XL6009/LM2577 solution. After the output voltage is set, it does not change with the input voltage. The current can be set to limit the output current, constant current drive, battery charging and other occasions. It has its own output anti-backflow function, so you don't need to add anti-backflow diode when charging the battery.
