10 Pcs Buck Converter 5V Regulator, 12V 24V to 5V 3A Mini Module for DIY, 4.5-24V Input Range, Chip Design, Compact PCB Board, Stable Volt Output

Voltage range: the power supply module input is DC 4.5 - 12V, adjustable range is 0.8 - 17V, fixed output is 1.8V, 2.5V, 3.3V, 5V, 9V, 12V which can be chosen on the back; Output current is 3A max, please increase the cooling work at full load; If the actual test input is 12V and output is 1.5A, no other system is required.
Adjustable and fixed voltage output: this buck converter allows you to get fixed output voltage by soldering the pot on the board, and you can adjust the fixed output voltage by potentiometer as you needed.
Product performance: the voltage regulator module has high efficiency, ultra-compact size, high frequency, low ripple and stable working performance, widely
applicable for fixing work: Synchronous rectification and the circuit conversion efficiency is as high as 97.5 %.
Reliable material: regulator module is made with quality potentiometer and 3A current chip, high current shielding inductor and MLCC solid capacitor with long service life; High current shielding inductance, ultra-low internal resistance, maximize conversion efficiency, reduce heat generation.
Convenient to use: integrated enable port of the regulator board defaults to working mode and will be closed when it is at low electric level off, and with ultra-low quiescent current, quiescent current is 0.85 mA; It can be connected to the car battery without a switch, cigarette lighter cord or the ACC power cord
