1pc Mini Step Down Power Module Converter DC-DC 4-24V 12V 24V to 5V3A,Default NO5245

Features:

1. Adopted imported chip.

2. With new design inside, the circuit design does not require electrolytic capacitors and tantalum capacitors (the electrolytic capacitor has a short life and the tantalum capacitor has the danger of explosion). The large-size solid ceramic capacitors (MCC) used in the high-end circuits are used.

3. Adopts synchronous rectification, and the circuit conversion efficiency is very high. When the 6.5V turns 5V 0.7A, the efficiency is as high as 97.5%, and when 12V turns 5V 1A, it also reaches 94%. Unlike the peers, the efficiency is only 60-70%. 

4. Adopt high current shielding inductance, ultra low internal resistance, increase the conversion efficiency and reduce the heat.

5. Ultra small size, 20* 11* 5mm.(L*W*H)

6. Ultra-low quiescent current, quiescent current 0.85 mA. Connected to the car battery without the need for a switch, can be connected to the cigarette lighter line, or ACC power line.

Module parameters:
