PM6680A is a dual step-down controller specifically designed to provide extremely high efficiency conversion, with losses current sensing technique. The constant on-time architecture assures fast load transient response and the embedded voltage feed-forward provides nearly constant switching frequency operation. An embedded integrator control loop compensate.
