Description
Specification
- Module nature: non-isolated step-down module (BUCK) synchronous rectification
- Input voltage: DC 4.5-24V
- Output voltage: integrated adjustable and fixed output, fixed output voltage can be selected on the back
- Adjustable range (0.8-17V), fixed voltage (1.8V 2.5V 3.3V 5V 9V 12V)
- Output current: 3A (please pay attention to heat dissipation at full load), the actual test input 12V output within 1.5A does not require special heat dissipation.
Features
1: The output current is 3A, long-term operation is 2.1A, and the margin is sufficient.
2: Adopting a new scheme design, the circuit design does not need electrolytic capacitors and tantalum capacitors
3: Improve conversion efficiency. Reduce heat generation.
4: Small size, 20 (length) * 11 (width) * 5 (height) mm.
5: Low quiescent current, quiescent current 0.85 mA. There is no need to add a switch when connected to the car battery, and it can be connected to the cigarette lighter line or the ACC power line.
6: The output is integrated with adjustable and fixed voltage. The fixed output does not need to be customized. It can be spot welded directly on the board. The voltage is very useful and can be adjusted with a potentiometer. It is very versatile.
7: Integrated enable port, the default is working mode, low level is closed, which brings convenience to control
Back side You can choose fixed output voltage
