Step-down Module DC-DC 6V-30V to 5/9/12V Mini Buck Module Power Converter Module

Home Arduino Module Sensor Chips About Us Item Description Features: 1.The module adopts imported chip, with low static power consumption, 500KHZ low ripple output, high conversion efficiency. 2. Small size, limited heat dissipation capacity, continuous use of current is recommended below 2A, the maximum voltage is recommended not to exceed 28V is appropriate. 3. Low ripple, multiple protection, safety, output short circuit protection, built-in over-temperature protection. 4. Product design, materials, PCB process with enough effort, so that the module can be done in a very small volume above the very impressive parameters and features. 5. High conversion efficiency, up to 93% conversion efficiency. Product parameters: Input: DC30V(Max) Current output:3A max Static current:0.6mA Conversion efficiency:up to 93% 500KHZ low ripple Output short circuit protection Built-in over-temperature protection Operating Temperature:-40℃ to +85℃ Short size:17mm*13mm*4.6mm Long size: 28mm*15mm*5.7mm Hole diameter: 2.6mm Main uses: low voltage step-down, digital products, MCU power supply, ripple requirements, slightly higher circuit step-down. Difference: the two boards are basically the same, the long board ripple a little better, a little stronger heat dissipation, after all, the volume is larger, the other differences are not great, you can choose according to demand. Module interface IN+: DC input positive 4.5V-30V (need to be higher than the output 1V or more). IN-:DC input negative terminal, connected with output negative terminal. Output +: DC output positive. Output-:DC output negative pole, connected with input negative pole. Product List: 1X module Note for use: ◆ The input of the product should be greater than the output voltage, and it is better to keep the voltage difference above 1V, and the input can not be connected in reverse, and the board will be burned when connected in reverse. ◆ When wiring, it is best to disconnect the power supply, otherwise when the voltage is high, it is easy to spark, so there will be a certain risk of striking the chip, breakdown chip. ◆ Wiring should not be too fine, ensure that the wire can withstand the corresponding current. ◆ Inductive loads should be well protected to avoid excessive reverse electromotive force beyond the range of the chip. ◆ The higher the power of the module, the closer the current is to the maximum current. Pay attention to heat dissipation when using the module. ◆When there is no additional heat dissipation, the continuous use current is recommended to be below 5A, more than 5A needs additional heat dissipation, otherwise it will overheat to protect the output. ◆ The use of voltage is recommended to be below 24V, because if the supply voltage is not very stable, the spike voltage over 25V will trigger the chip internal over-voltage protection, in order to stabilize the operation, leave some margins appropriately. ◆ When the use of problems, contact customer service must cooperate with customer service to provide wiring pictures, use video, etc., do not accept only provide text information.
