1. Input voltage: DC 3.2~40V
2. Output voltage: 1.25~35V
3. Output current: 3A
4. Output ripple: Less than 30mv
5. Switching frequency: 65Khz
6. Working temperature: -45 to 85 degrees Celsius
7. Size: 43x21x14mm
8. Note: This is a step-down module, and the input voltage needs to be higher than the output voltage. The output current is greater than 2.5A (or the output power is greater than 10W), please add a heat sink to work for a long time
