AT6903Z
AT6903Z Synchronous Rectification Driver IC
AT6903Z Synchronous Rectification Driver IC
General Description
AT6903Z is a secondary side Synchronous Rectification driver IC to drive SR MOS replaces Schottky rectification diode for higher efficiency. With adaptive dead time control method, AT6903Z could operates in DCM and CCM safely without cross conduction issue. In system light load condition, AT6903Z enter light load mode and stop Gate switching result to less standby power loss.
The devices are available in SOT23_5L package and require few external devices for operation.
