TPS54331

(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device eliability.

The TPS54331 is a 28-V, 3-A non-synchronous buck converter that integrates a low Rds(on) high side pMuOlsSeFEskTip. pTinog inEccroe- msoedee™fficifeenactuyreatisligahuttomloaadticsa, llay activated. Furthermore, the 1 mA shutdown supply current allows the TPS54331 to be used in battery powered applications.

A resistor divider programs the hysteresis of the input under-voltage lockout. An overvoltage transient protection circuit limits voltage overshoots during startup and transient conditions. A cycle by cycle current limit scheme, frequency fold back and thermal shutdown protect the TPS54331 and the load inthe event of an overload condition.
