USB Step-down 12/24V to 5V 3A Mini DC Power Module Using a MP2315

Board Features: The maximum output current of 3A, 2.1A long run, sufficient margin. Using a new design, circuit design does not require electrolytic capacitors and tantalum capacitors (electrolytic capacitor life is short, tantalum capacitors have the risk of explosion). Using the current high-end circuit with large-size solid-state ceramic capacitors (MCC) 3pcs. Ripple is very low, 12V to 5V 3A only 10 mV or so, a lot of ripple rivals have reached 500 mV or greater, the equipment will cause an invisible injury, serious equipment will cause abnormal or damaged, IPHONE Very delicate. The new solution uses synchronous rectification, the circuit conversion efficiency is very high, in the 6.5V to 5V0.7A when the efficiency of up to 97.5%, 12V to 5V1A also reached 94%, unlike some efficiency of only 60-70% peers. (The efficiency test removes the voltage drop across the input reverse-polarity protection diodes and fuses). Use of flat copper inductors, to maximize the conversion efficiency. Reduce heat. The first with output over-voltage protection, input 1.5A fuse, output 5V 300W TVS tube over-voltage clamp protection to protect USB devices are now peer USB buck module are not over-voltage protection, the USB device There is a very large security risk, think about it put it on your iphone or other phones Using the latest USB identification circuit, perfectly compatible with IPHONE, the vast majority of android mobile phones, IPAD. Short gold-plated edge USB, long life, a normal USB interface can match. Output voltage indicator (red)Ultra – small size, 26.4 (L) * 15 (W) * 7.4 (H) mm. Input with a reverse polarity protection diode, input positive and negative polarity will not be damaged, (OUR test efficiency ignores the input diode and fuse voltage drop) Ultra-low quiescent current, quiescent current 0.85 mA. Connect to the car battery without adding the switch, you can connect the cigarette lighter line, or ACC power line. Board Specifications: Input voltage: DC 6-24V, Output voltage: 5.1-5.2V Output current: maximum 3A (full load, please pay attention to heat), the actual test input 12V output 2A no special treatment within the cooling. Conversion efficiency: up to 97.5% (6.5 to 5V 0.7A) (short-circuit reverse polarity protection and fuse after the test value) Switching frequency: 500KHz Output ripple: 10mV or so (12V to 5V3A) 20M bandwidth Output indication: The output voltage indicator is red Operating temperature: industrial (-40 ℃ to + 85 ℃) (the higher the ambient temperature, the smaller the output power) Output overvoltage protection: yes, input 1.5A fuse, output 5V 300W TVS tube clamp protection. Full load temperature rise: 30 ℃ Quiescent Current: 0.85 mA Load regulation: ± 1% Voltage regulation: ± 0.5% Dynamic response speed: 5% 200uS Output short-circuit protection: Yes, do not short-circuit for a long time Input reverse polarity protection: Yes, input reverse polarity protection diode Price is for one unit only.
