1Pcs Voltage Regulator Pcb Board Module Output 8A Dc-Dc 25V To 3.3V/5V/9V/12V Buck Step Down Converter Board Module

Description Parameters: Input: DC 25V (maximum) Output: 3.3V/5V/9V/12V Current output: 8A (maximum) Quiescent current: 0.1mA Conversion efficiency: up to 95% Low ripple: 500KHZ Output short-circuit protection Built in over temperature protection Operating temperature: -40 ° C to+85 ° C 5/9/12/24V optional Main uses: low-voltage voltage reduction, unmanned power supply, MCU power supply, ripple requirements, slightly higher circuits Material: Plastic+Metal Size: As picture Attention: The module has a relatively small volume and limited heat dissipation area. It is normal for high-power output to generate heat. The back of the board can be directly attached to the surface of a fixed object to enhance heat dissipation. The board has a thickness of 7.4mm and includes heat dissipation fins. For applications with high power consumption requirements, the output LED indicator light can be removed. Module interface: VIN+: DC input positive pole 6V-25V (must be higher than output voltage by more than 1V). GND: DC input negative pole, connected to output negative pole. +(OUT+): DC output positive pole. -(GND): DC output negative electrode, connected to input negative electrode. Package include: 1pcs * Step Down Converter Board Module Instructions for use: 1.The input of the product should be greater than the output voltage, and it is best to maintain a voltage difference of more than 1V. The input should not be connected in reverse, and the circuit should be connected in reverse. 2.It is best to disconnect the power supply when wiring, otherwise when the voltage is high, it is easy to spark, which will have a certain risk of hitting the chip and breaking it down. 3.The wiring should not be too thin to ensure that the wire can withstand the corresponding current. 4.Protect the inductive load to avoid excessive reverse electromotive force exceeding the range of the chip. 5.The higher the power used by the module, the closer the current is to the maximum current. The heat will increase, so pay attention to heat dissipation when using. 6.When there is no external heat dissipation, it is recommended to continuously use a current below 5A. If the current exceeds 5A, additional heat dissipation is required, otherwise overheating protection output will occur. 7.The recommended voltage for use is below 24V. If the power supply voltage is not very stable and the peak voltage exceeds 25V, it will trigger the internal overvoltage protection of the chip. For stable operation, some margin should be left appropriately. Note: 1.
