Notes
- The XL4015 is a module-based buck converter, not a discrete IC. Connections are made via screw terminals (IN+, IN−, OUT+, OUT−) and potentiometer adjustments (CV, CC).
- Input voltage must be higher than desired output voltage (step-down operation).
- Maximum output current is adjustable up to 5 A.
- Switching frequency: 300 kHz; Output ripple: ≤50 mV (20 MHz bandwidth).
- Operating temperature range: −40 °C to +85 °C.
- The pin diagram image provided did not contain explicit numbered pins; the numbering above reflects the functional connections described in the datasheet and typical module layout conventions.
