GS5453A Datasheet | Globaltech

Description The GS5453A is a high frequency, synchronous, rectified, step-down, switch-mode converter with internal power MOSFETs. It offers a very pact 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 GS5453A requires a minimal number of readily available, external ponents and is available in a space saving SOT-563 package.
