The margin is sufficient.2: Designed with a new solution, the circuit design does not require electrolytic capacitors and tantalum capacitors3: Improve conversion efficiency. Reduce heat.4: small volume, 20 (length) * 11 (width) * 5 (height) mm.5: Low quiescent current, quiescent current 0.85 mA. Connected to the car battery without a switch, can be connected to the cigarette lighter line, or ACC power line.6: The output is integrated with adjustable and fixed voltage. The fixed output is not required to be customized. It can be directly soldered on the board. It is very voltage-sensitive and can be adjusted by potentiometer. It is very versatile.7: Integrated enable port, default is working mode, low level is off, which brings convenience to controlModule parameterModule nature: non-isolated buck module (BUCK) synchronous rectificationInput voltage: DC 4.5-24VOutput voltage: integrated adjustable and fixed output, fixed output voltage on the backAdjustable range (0.8-17V), fixed voltage (1.8V 2.5V 3.3V 5V 9V 12V)Output current: maximum 3A (please pay attention to heat dissipation at full load), the actual test input 12V output within 1.5A without special treatment heat dissipation.Conversion efficiency: up to 97.5% (6.5 to 5V 0.7A) Switching frequency: 500KHz Output ripple: 20mV (12V to 5V3A) 20M bandwidthOperating temperature: industrial grade (-40 ° C to +85 ° C) (the higher the ambient temperature, the lower the output power)Output overvoltage protection: none Full load temperature rise: 40 ° CQuiescent current: 0.85 mA Load adjustment rate: ±1% Voltage regulation rate: ±0.5%Dynamic response speed: 5% 200uSOutput short circuit protection: Yes, do not short circuit for a long time Input reverse connection protection: none, input reverse connection protection diodeEnable control: Yes, high level operation, low level stop working, high level is 2-5V, low level is about 0V. The default internal pull-up to input positive. Wiring method: welding Input method: welding Output method: welding / pin header Welding hole spacing: 2.54 mmFAQ1.Are you manufacturer ?Yes, We Are Manufacturer & Trading Company2.How long is your delivery time?Normally 3-5 working days after payment; Special requirement orders, delivery time is negotiable.3.Do you accept OEM design?Yes, we do.
