## Description

CC-CV step-down module for precise voltage and current regulation, ideal for battery chargers and constant current LED power supply. Offers adjustable output 1.25-36V and 0-5A up to 75W, stabilization in CV mode or limiting in CC mode, thermal and short-circuit protection, compact format for quick integration into projects.
Step-down voltage and adjustable current module, suitable for making a lithium battery charger and other projects that require voltage and current control. The module features CC and CV functions.
The module can be used as:
- General step-down module with overcurrent protection
- Lithium, Ni-Mh, etc. battery charger... As a battery charger, once the "float" voltage is set, the LED indicator will signal the completion of charging.
- Constant current power supply for LEDs
