Overview
The SK6637 is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very compact solution to provide a 3A continuous output current over a wide input supply range, with excellent load and line regulation. ECOT control operation provides very fast transient response and easy loop design as well as very tight output regulation. The SK6637 requires a minimal number of readily available, external components and is available in a space saving SOT563 package.
