diymore DC 6-80V to 3.3V5V12V1.2A output High power DC power supply module Low ripple high conversion

ParameterInput voltage: 6-80V (need to be higher than the output of more than 5%) Output voltage: Fixed 3.3V 5V 12V (optional) Output current: 1.2A Maximum peak current: 1.5A Efficiency: >90Precautions:1. The product input should be greater than the output voltage, to maintain a pressure difference of more than 2V is best, the input can not be reversed, reversed burn plate2. Wiring is best to disconnect the power supply, otherwise when the voltage is high, it is easy to spark, so there is a certain risk of breakdown of the chip3. Inductive loads to do a good job of protection, to avoid excessive reverse electromotive force beyond the chip's tolerance range4. The more power the module uses, the closer the current is to the maximum current. The greater the heat will be, pay attention to the use of heat dissipation5. In the absence of external heat dissipation, the continuous use of current is recommended below 1A, more than 1A requires additional heat dissipation, otherwise it will overheat to protect the output.6. The use of voltage is recommended to 76V or less, because if the supply voltage is not very stable, the spike voltage exceeds 80V will trigger the chip internal over-voltage protection, for stable operation, appropriate to leave some margin!Package includeModule*1
