Description
Output Current: 3A, long-term operation at 2.1A with sufficient margin.
New Design Scheme: The circuit design does not require electrolytic capacitors and tantalum capacitors.
Improved Conversion Efficiency: Reduces heat generation.
Compact Size: 20mm (L) * 11mm (W) * 5mm (H).
Low Quiescent Current: 0.85mA. Can be connected to a car battery without an additional switch, can be connected to the cigarette lighter line or ACC power line.
Integrated Adjustable and Fixed Voltage Output: Fixed output no longer needs customization, can be directly spot welded on the board. For uncommon voltages, the potentiometer can be used for adjustment, offering strong versatility.
Integrated Enable Port: Default is working mode, low level to turn off, providing convenient control
