USB Step Down Module 6-24V to 5V 3A DC-DC Buck Converter for Phone Charger Car Power Supply

This listing offers either a set of 2pcs or 6pcs of the 3A USB Step Down Module. It is a DC-DC converter that can convert input voltages ranging from 6V to 24V to a stable 5V output with a maximum current output of 3A. The converter boasts a high efficiency rate of 97.5% and is designed as a buck converter. Made from durable materials, this module does not include a battery and is commonly used for phone chargers or as a power supply for cars.

The maximum output current is 3A, with a continuous usage of 2.1A, which is sufficient. It features a new design with three solid-state ceramic capacitors (MLCC). The synchronous rectification allows for high efficiency, achieving up to 97.5% from 6.5V to 5V at 0.7A, and up to 94% from 12V to 5V at 1A. The flat copper inductor enhances conversion efficiency.This device features protection against output overvoltage. It includes a 1.5A fuse and a 5V output with a 300W TVS tube to safeguard your USB devices. It utilizes the latest USB identification technology, ensuring compatibility with iPhones, most Android phones, iPads, and more. The USB port is of high quality, and there is a red indicator for the output voltage.The device features a reverse polarity protection diode, ensuring it remains unharmed if the input is connected incorrectly. It consumes an extremely low static current of just 0.85 mA. There's no need to include a switch when linking it to the car battery; it can be directly connected to the car's cigarette lighter cable or the ACC power supply cable.Module Specifications: non-isolated buck converter (BUCK) with synchronous rectification. Input voltage range: DC 6-20V. Output voltage range: 5.1-5.2V. Maximum output current: 3A. Conversion efficiency can reach up to 97.5% (for a 6.5V to 5V conversion at 0.7A) (after testing for short reverse protection and fuses). Switching frequency: 500KHz. Output ripple: approximately 10mV (from 12V to 5V at 3A) with a 20M bandwidth. Output indicator: the output voltage indicator is red.Working temperature: Industrial standard (-40 degrees Celsius to +85 degrees Celsius) (as the surrounding temperature increases, the output power decreases). Overvoltage protection for output: Yes, includes a 1.5A fuse for input and a 300W TVS tube clamp protection for the 5V output. Maximum load temperature: 30 degrees Celsius.Static current is 0.85 mA, with load regulation at ± 1% and voltage regulation at ± 0.5%. The dynamic response speed is 5% at 200 microseconds. There is output short circuit protection, but it is advised not to short circuit for extended periods. Input reverse polarity protection is available, featuring a reverse polarity protection diode. The connection mode is welding, and both input and output modes are also welding.
