PM6680TR Description
PM6680TR is a No Rsense dual step-down controller with adjustable voltages for notebook system power. Utilizing a lossless current sensing technique, it provides extremely high-efficiency conversion. Fast load transient response can be achieved due to its constant on-time architecture and Nearly constant switching frequency operation can be delivered thanks to the embedded voltage feed-forward. In addition, the pulse skipping technique is used to improve efficiency at a very light load. The PM6680TR is embedded in the VFQFPN-32 package.
