Detailed Product Description

 Power Management IC TPS54331DR AC to AC Converter SOP-8 Voltage Chip with Eco-mode

Description

 

The TPS54331 device is a 28-V, 3-A non-synchronous buck converter that integrates a lowRDS(on) high-side MOSFET. To increase efficiency at light loads, a pulseskipping Eco-mode feature is automatically activated.

 

Furthermore, the 1-µA shutdown supply-currentallows the device to be used in battery-powered applications. Current mode control with internalslope compensation simplifies the external compensation calculations and reduces component countwhile allowing the use of ceramic output capacitors. A resistor divider programs the hysteresis ofthe input undervoltage lockout. An overvoltage transient protection circuit limits voltageovershoots during startup 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 overloadcondition.

 

The TPS54331 device is available in an 8-pin SOIC package and 8-pin SO PowerPAD packagethat have been internally optimized to improve thermal performance.
