In the world of power supply design, few components are as critical—or as widely misunderstood—as the PWM (Pulse Width Modulation) controller. Among the myriad of options available to engineers and repair technicians, the stands out as a highly specialized, dual-output controller. While not a household name, this IC is a workhorse found on numerous motherboards, graphics cards, and embedded systems, particularly those manufactured in the late 2000s and early 2010s.
