DC-DC 9A 300W DC Step-Down 7-40V to 1-35V CC CV

DC-DC 9A 300W DC Step-Down 7-40V to 1-35V CC CV

Due to the discontinuation of 12A current chip manufacturers, the replacement chip current is reduced from 12A to 8A (the maximum current actually tested is about 9A), the input voltage is increasedfrom the previous 32V to 40V , and the output voltage is  increasedfrom the previous 28V to 35V .
