PM6680 Datasheet - STMicroelectronics

PM6680 No Rsense dual step-down controller

PM6680 is a dual step-down controller specifically designed to provide extremely high efficiency conversion, with lossless current sensing technique. The constant on-time architecture assures fast load transient response and the embedded voltage feed-forward provides nearly constant switching freque.
