What are the key features of the TPS54331?

Key features include a 3.5V to 28V input range, 570kHz fixed switching frequency, pulse-skipping Eco-mode™ for light-load efficiency, and programmable slow-start and UVLO.

Eco-mode™ is a pulse-skipping feature that automatically activates at light loads to reduce switching losses and improve overall efficiency.

What should engineers consider when designing with the TPS54331?

Engineers should carefully select the output filter (L and C) and compensation components, as the device is externally compensated. Proper PCB layout is also critical to minimize noise and heat.

What should sourcing teams check before buying TPS54331DR?

Check lifecycle (Active), compliance data, distributor availability, and approved-source coverage. Current sourcing signal: Low; readiness: easy.

What is the pinout of TPS54331DR?

Use the TPS54331DR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about TPS54331DR pinout to locate pins, power rails, and interface signals before layout.
