1. Product description: The default patch is a small current model, the MAX version needs to be customized - naturally the cost is high
1. PCB800118 is a boost type, full patch, and the inductor is a high-quality integrated inductor.
2. The input voltage range of PCB800118 is 4-14V. If it exceeds this voltage range, it may not work properly or be damaged.
3. The output voltage of PCB800118 ordinary model is more than 3V higher than the input voltage, and the output voltage is about 7V-26V. For the MAX version, the maximum output voltage can reach 36V (customization is required)
4. PCB800118 low-current model inputs 12V voltage, and the maximum output safe working current does not exceed 200MA. (The working current in normal settings can reach about 150MA. You can also set the output current by yourself through a resistor.) The maximum current of the MAX version can reach 1A, which is required. custom made
5. The maximum voltage of the EN pin of PCB800118 cannot exceed 3.3V, otherwise the main chip will be damaged.
6. PCB800118 has three output ports, two 3.5 LED interfaces and one 4P-2.0 interface.
7. The PCB of PCB800118 is made of FR4 flame retardant material (not cardboard) with a thickness of 1.6MM, which maximizes the safety of the product and ensures that the product does not deform after long-term use.
8. Adjust the size of PCB800118----, R33 and R34 to adjust the output current.
9.PCB800118-----The effective voltage of EN pin shutdown needs to be less than 0.5V
10. PCB800118---The effective power-on voltage of EN pin needs to be greater than 2.5V but not more than 5V
11. PCB800118 size is 38.45X23.45MM
The above parameters are the basic technical parameters of PCB800118, please check carefully before use.
