ST PM6680A handbook
The PM6680A is a dual step-down controller from STMicroelectronics that provides up to 98% conversion efficiency. It uses a constant on-time architecture to ensure fast load transient response and an embedded voltage feed-forward to provide nearly constant switching frequency operation. An embedded integrator control loop compensates for output ripple-induced DC voltage error. Pulse skip technology increases efficiency at very light loads. Additionally, a minimum switching frequency of 33kHz is selectable to avoid audio noise issues. The PM6680A provides a selectable switching frequency, allowing selection between 1.5MHz, 2.5MHz, and 4MHz.
