The TPS54331 device is a 28-V, 3-A nonsynchronous buck converter that integrates a low RDS(on) high-side MOSFET. To increase efficiency at light loads, a pulse skipping Eco-mode feature is automatically activated. Furthermore, the 1-μA shutdown supply-current allows the device to be used in battery-powered applications. Current mode control with internal slope compensation simplifies the external compensation calculations and reduces component count while allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis of the input undervoltage lockout. An overvoltage transient protection circuit limits voltage overshoots during start-up and transient conditions. A cycle-by-cycle current-limit scheme, frequency foldback and thermal shutdown protect the device and the load in the event of an overload condition. The TPS54331 device is available in an 8-pin SOIC package and 8-pin SO PowerPAD integrated circuit package that have been internally optimized to improve thermal performance. • 3.5 to 28-V input voltage range • Adjustable output voltage down to 0.8 V • Integrated 80-mΩ high-side MOSFET supports up to 3-A continuous output current • High efficiency at light loads with a pulse skipping Eco-mode • Fixed 570-kHz switching frequency • Typical 1-μA shutdown quiescent current • Adjustable slow-start limits inrush currents • Programmable UVLO threshold • Overvoltage transient protection • Cycle-by-cycle current limit, frequency foldback, and thermal shutdown protection • Available in easy-to-use SOIC8 package or thermally-enhanced SOIC8 PowerPAD™ integrated circuit package • Create a custom design using the TPS54331 with the WEBENCH® Power Designer • Use TPS62933 for a 30 VIN converter with higher frequency, lower IQ and improved EMI #CommonPartsLibrary #IntegratedCircuit #PowerManagement
