PM6680 Datasheet (STMicroelectronics) - No Rsense dual step-down controller

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
