AITIAO 20Pcs 5V Regulator Module Mini Voltage Reducer DC 4.5-24V 12V 24V Step Down to 5V 3A Buck Converter Reduced Voltage Regulator Power Supply Transformer Module








Key features
- •AITIAO Voltage Regulator Parameter: Input voltage range: DC 4.5-20V; Adjustable range: 0.8-17V;Fixed output: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V (can be chosen on the back side). Output current: 3A max (please enhance cooling work when it is full load); When real tested input 12V and output is 1.5A, no need to add special system.
- •Mini Voltage Reducer 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%
- •Adjustable and fixed voltage output: you can obtain a fixed output voltage by mounting a potentiometer on the voltage regulator module board; you can also adjust the fixed output voltage by potentiometer as required.
- •Quality material: regulator module is made with quality potentiometer and 3A current chip, high current shielding inductor and MLCC solid capacitor with long service life, ultra-low internal resistance, maximize conversion efficiency, reduce heat generation
- •Simple to operate: integrated design allows port of the regulator board defaults to keep working mode and will be closed if it is at low electric level off, and with ultra-low quiescent current of 0.85 mA; It can be connected to the car battery without a extra switch, car female socket or the ACC power cord, convenient to use
