Based on the part number, is a common 12V, 1.66A (20W) switching power supply board, often found in LED drivers, small monitors, routers, or security cameras.
Do not settle for the original, failure-prone revision. When searching for your next 12V/15A power supply, make "patched" the minimum requirement. Your equipment—and your sanity—will thank you.
It typically utilizes NPN-type bipolar junction transistors (BJTs) or MOSFET switches to manage the high-speed switching required for efficient power delivery. Common Failure Points & "Patch" Requirements
