HiLetgo 10pcs Mini DC-DC 12-24V to 5V 3A Step Down Buck Power Module Fixed Voltage Output 1.8V 2.5V 3.3V 5V 9V 12V Optional Adjustable Efficiency 97.5%

Descritpion: This Mini DC Buck Module uses synchronous rectification circuit conversion efficiency is very high, in turn 5V 0.7A 6.5V when efficiency up to 97.5%, 12V turn 5V 1A, they also reached 94%, unlike some others efficiency is only 60-70%. Ultra-low quiescent current, quiescent current of 0.85 mA. Connected to the car battery without adding switches can be connected to the cigarette lighter line or the ACC power cable line. The new design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum risk of explosion). Now with the use of high-end large-size solid ceramic capacitor circuit (MCC) 2 Ke. Big shielded inductor current, low resistance, to maximize conversion efficiency, reduce heat. Features: Input Voltage: DC4-18V Fixed voltage output optional: 1.8V 2.5V 3.3V 5V 9V 12V Output Current: 3A (max), must strengthen heat dissipation Transform Efficiency: 97.5%(max) (6.5 to 5V 0.7A) Switch Frequency: 500KHz Output Ripple Wave: 20mV (12V to 5V 3A) 20m band width Operating Voltage: -40 Celsius-85 Celsius Output Overvoltage Protection: no Static Current: 0.85MA Load Adjust Rate: ±1% Voltage Adjust Rate: ±0.5% Dynamic Response Speed: 5% 200uS Output Short Circuit Protection: yes Reverse Protection: no Connecting Type: soldering Soldering Space: 2.54mm Package Included: 10 x Mini DC-DC 12-24V to 5V 3A Adjustable Step Down Buck Module
