70v to 12v chip, wide input voltage: 4.5V to 80V, output voltage can be from 0.8V to 30V, to 12v can work for a long time with rated current. The 70v to 12v solution is adjustable.
The conversion efficiency of the 70v to 12v chip is as high as 90%. There are not many foreign components because of the built-in mso. The normal operation is below 600MA, and it does not generate much heat. If you need more than 12v1A current
We have to switch to another 70v to 12v chip with external MOS, and its maximum output current can reach 2A.
70v to 12v chip, sop8 package with short circuit protection, over temperature protection, over current protection, and en pin.
