XL4015 Step Down Charge Module 5A Adjustable Power CC/CV with Display

From the shop's description

XL4015 Step Down Charge Module 5A Adjustable Power CC/CV with Display The XL4015 Step Down Charge Module 5A Adjustable Power CC/CV with Display is a high-performance DC-DC buck converter designed for applications requiring adjustable output voltage and current limiting. Based on the XL4015 switching regulator, this module converts a higher DC input voltage into a lower regulated output voltage with excellent efficiency while supporting both Constant Voltage (CV) and Constant Current (CC) operating modes. Features: Compact size Built-in display of output voltage and current Output voltage adjustment Output current limit adjustment XL4015 step-down converter Output current up to 5A with cooling and 3A without cooling Input voltage range 5 to 30V Output voltage range 0.8 to 29V Specifications: Maximum Ratings Vin Maximum Input Voltage 30V I O Maximum Output Current 5A Operating Ratings Vin Input Voltage Range 5 – 30V Vout Output Voltage Range 0.8 – 29V I O Output Current (max continuous) 3A (without air cooling) 5A (with forced air cooling) Display Measurement Stated Accuracy 0.1% (less in practice) Switching Frequency 180kHz Output Ripple Varies depending on load < 50mV (measured) Efficiency Varies depending on load 85% (typical measured) 95% max Electrical Isolation Non-isolated Dimensions L x W x H 51 x 26 x 20mm Configuration: TTL Interface Connector: The 3-pin white JST style connector brings out the TTL serial interface from the STM8S003F3 micro that is used on the display board. In theory, it is possible to retrieve the voltage and current readings from the device through this interface though it appears to be pretty clunky.
