MINI Size DC/DC Buck Adjustable Step-Down Module 4.5-24V To 1.8v, 2.5v, 5v, 9v and 12v, 3A

MINI Size DC/DC Buck  Adjustable  Step-Down Module 4.5-24V  To 1.8v, 2.5v, 5v, 9v and 12v, 3A

MINI Size DC/DC Buck Adjustable  Step-Down Module 4.5-24V  to 1.8v, 2.5v, 5v, 9v, 12v,3A 


introduction

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

2: A new design is adopted , and the circuit design does not require electrolytic capacitors and tantalum capacitors

3: Improve conversion efficiency. Reduce heat. 

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 to the car battery, 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.

It is very useful for voltage and can be adjusted with a potentiometer. It is very versatile

7: Integrated enable port, the default is the working mode, the low level is closed, which brings convenience for control
