TPS54228DRCT

Voltage Regulators - DC DC Switching Regulators Overview

The TPS54228DRCT is a synchronous step-down DC/DC converter from Texas Instruments, utilizing D-CAP2 and Eco-Mode technologies. It operates with an input voltage range of 4.5V to 18V and provides an adjustable output voltage between 760mV and 7V. The device delivers a maximum continuous output current of 2A at a fixed switching frequency of 700kHz. It features a low quiescent current of 800µA and supports operation within an ambient temperature range of -40°C to +85°C. The component is housed in a compact VSON-EP-10 package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRCT corresponds to the VSON-EP-10 package and tape-and-reel delivery format. Confirm RoHS compliance status and manufacturing origin through official datasheets or authorized distributor documentation before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a 2A synchronous buck solution is required with a wide input voltage range up to 18V. The fixed 700kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the application benefits from the integrated D-CAP2 topology which simplifies layout and stability requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS54228 family of synchronous buck converters. It shares architectural similarities with the TPS54328 but offers a lower 2A output current rating. The series is designed for applications requiring high efficiency and minimal external component count within a small footprint.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS54228DDAR is a pin-compatible alternative in an 8-SOIC package. Verify that the thermal performance and physical dimensions of the SOIC package meet the design constraints if substituting the VSON-EP-10 variant.
