Because the 8682L is packaged in a tight QFN-16 envelope, thermal performance hinges heavily on proper printed circuit board (PCB) geometry:
: Receives raw power input from the external DC power supply brick (usually 19V to 20V in legacy laptops).
Evelyn’s pulse quickened. The 8682L was rated for harsh conditions, but a rapid, unexplained heat spike meant a possible failure in the power conversion layer. If the temperature rose above , the orchids would crisp in minutes. 8682l Datasheet
