The TPS54331 is a 28-V, 3-A non-synchronous buck Integrated 80 mΩ High Side MOSFET Supports up to 3A Continuous Output Current converter that integrates a low Rds(on) high side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode™ feature is automatically High Efficiency at Light Loads with a Pulse activated. Furthermore, the 1 A shutdown supply Skipping Eco-mode™ current allows the device to be used in battery Fixed 570kHz Switching Frequency Typical 1A Shutdown Quiescent Current powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component Adjustable Slow Start Limits Inrush Currents count while allowing the use of ceramic output Programmable UVLO Threshold Overvoltage Transient Protection capacitors. A resistor divider programs the hysterisis of the input under-voltage lockout. An overvoltage transient protection circuit limits voltage overshoots Cycle by Cycle Current Limit, Frequency Fold during startup and transient conditions. A cycle by Back and Thermal Shutdown Protection cycle current limit scheme, frequency fold back and Available in Easy-to-Use SOIC8 Package Supported by SwitcherPro™ Software Tool (http://focus.ti.com/docs/toolsw/folders/print/s witcherpro.html) For SWIFT™ Documentation, See the TI Website at www.ti.com/swift thermal shutdown protect the device and the load in the event of an overload condition.
