PM6686 General Description

The PM6686 is a highly efficient dual step-down controller that offers superior conversion capabilities, thanks to its lossless current sensing technique. Its constant on-time architecture ensures rapid load transient response, while the embedded voltage feed-forward feature maintains nearly constant switching frequency operation. To further enhance efficiency, the pulse skipping technique is employed to optimize performance at very light loads. Users can select from a minimum switching frequency of 33 kHz to prevent any potential audio noise disruptions. With the ability to program and regulate output voltages of 1.5 V/5 V and 1.05 V/3.3 V, or to provide adjustable output voltages, the PM6686 offers versatile solutions for various applications
