Product Description

The TPS54331DR device is a 28V, 3A non-synchronous buck converter that integrates a low RDS(on) high-side MOSFET. The automatic activation of the pulse-skipping Eco-mode feature enables the TPS54331DR device to improve efficiency under light load conditions. In addition, the TPS54331DR device's 1µA shutdown supply current makes it useful for battery-powered applications.

External compensation calculations are simplified under current-mode control with internal slope compensation, while reducing component count while allowing the use of ceramic output capacitors.

A resistor divider programs the hysteresis of the input undervoltage lockout. Overvoltage transient protection circuitry limits voltage overshoot during startup and during transient conditions. A cycle-by-cycle current limit scheme, frequency foldback, and thermal shutdown features protect the device and load from overload conditions.

The TPS54331DR device is available in 8-lead SOIC and 8-lead SOPowerPAD packages that are internally optimized for improved thermal performance.

The TPS54331DR device is suitable for consumer applications such as set-top boxes, CPE equipment, LCD displays, peripherals and battery chargers, industrial and automotive audio power supplies and 5V, 12V, 24V distributed power systems.
