TPS54331DR Integrated Circuit IC chip

short description:

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

Switching regulators are the most efficient way to convert one DC voltage to another DC voltage. And across all non-isolated DC/DC topologies – buck, boost, buck-boost and inverting – we help you maximize the performance of your voltage regulator IC with the industry’s largest selection of DC/DC converters, power modules and controllers.

Power density

More power, less board space. Highlighted by the SWIFT™ buck regulator family, our portfolio of high-power density devices are highly integrated, with high-performance feature sets and high output-current capability in compact, thermally-enhanced packaging.
High-density switching regulators are a great choice to power high-current digital loads such as FPGAs and processors. Use our processor-attach tool to find the best products to complement your FPGA or processor.

Low EMI

Mitigating switching regulator EMI can be a major challenge for many power-supply designers. Devices with built-in EMI-reduction technologies save design time while helping you comply with difficult standards such as CISPR 25 Class-5. Take a look at our featured products below for some of the latest and best DC/DC switchers for EMI performance.

Low quiescent current (IQ)

DC/DC switching regulators with ultra-low quiescent current increase light-load efficiency and extend battery life in portable and battery-operated applications. Find some of the lowest IQ devices in our switcher portfolio below.

Low noise & precision

Typical switching regulators require a post-regulator LDO to power high-resolution ADCs and AFEs. But with the industry's best noise and ripple performance, TPS62912 and TPS62913 allow you to remove that low-noise LDO in most applications, saving PCB area and overall cost while improving system efficiency.
