GS5471 High-Efficiency, 2.5A, 21V, 500kHz Synchronous, Step-Down Converter Product Description The GS5471 is a high-frequency, Synchronous, Rectified, Step down, Switch-mode converter With internal power MOSFETs. It offers a very compact solution to achieve a 2A continuous output current over a wide input supply range, with excellent load and line regulator. The GS5471 has synchronous-mode operation for higher efficiency over the output current-load range. Current-mode operation provides fast transient response and eases loop stabilization. Protection features include over-current protection and thermal shutdown. The GS5471 requires a minimal number of readily available, standard external components and is available in space-saving TSOT-23-6L package. Features  Wide 4.
