The solution is based on the EG1190 chip, using a non-isolated BUCK architecture to achieve an output of 5V3A or 12V3A. It has a wide input voltage range (11V - 85V when outputting 5V, and 18V - 85V when outputting 12V), with a maximum efficiency of 93.09% (when outputting 12V). It features adjustable output voltage and peak current, and can be customized with an enable control line. The overall solution is reasonably designed and may offer certain cost advantages.
