Description
XL4005 5 A CC-CV Step-Down Converter
This XL4005 buck module has adjustable output-voltage and constant-current controls. A third potentiometer sets the current threshold at which the OK LED illuminates. The indicator reports that the load current has fallen below the selected threshold; it does not independently determine that a battery is fully or safely charged.
Applications listed by the source
- Powering high-power LEDs that require constant current
- CC/CV power-supply projects
- The source mentions battery, solar-panel and wind-power applications; verify system requirements and use appropriate controls

Safety and setup
This CC/CV module is not a chemistry-aware battery charger. Do not rely on a generic voltage/current example for charging; select a charge profile and independent protection appropriate to the specific battery. Reverse-polarity protection is limited to input current up to 2 A; do not assume protection at higher current. Set and verify voltage/current limits before connecting a load. Datasheet
