MINI efficiency 97.5% small volume DCDC step-down module 4-24V12V24V to 5V3A car


New product introduction:

1: The output current is up to 3A , and the long-term operation is 2.1A, and the margin is sufficient.

2: Designed with a new solution , the circuit design does not require electrolytic capacitors and tantalum capacitors

3: Improve conversion efficiency. Reduce heat. 

4: small volume, 20 (length) * 11 (width) * 5 (height) mm.

5: Low quiescent current, quiescent current 0.85 mA . Connected to the car battery without a switch, can be connected to the cigarette lighter line, or ACC power line.

6: The output is integrated with adjustable and fixed voltage. The fixed output is not required to be customized. It can be directly soldered on the board. It is very voltage-sensitive and can be adjusted by potentiometer. It is very versatile.

7: Integrated enable port, default is working mode, low level is off, which brings convenience to control
