The BD9227F is the industry's first power supply IC capable of controlling the rotational speed of DC fan motors with high accuracy by linearly varying the output voltage based on the PWM duty ...

It includes a 6-speed fan speed control system, boost mode, and timer via remote. The integrated LED light functions as a night lamp, adding utility and ambiance.

In many new designs, smaller packaging, ever-shrinking boxes, and high-power ICs can cause heat problems. Fans can minimize overheating, but unfortunately, they are prone to mechanical problems, ...
