TPS54229DDAR Description

Short technical summary and product information.

The Texas Instruments TPS54229DDAR is a highly efficient synchronous step-down (buck) converter designed for power management applications. It accepts an input voltage range of 4.5V to 18V and can deliver up to 2A of output current.

 

The device features an adjustable output voltage, with a minimum output of 0.76V and a maximum of 7.0V. Its integrated FETs optimize performance for lower duty cycle applications, offering a high-side resistance of 160 mΩ and a low-side resistance of 110 mΩ. The switching frequency is set at 650kHz, contributing to a compact solution size.

 

Designed for ease of use, the TPS54229DDAR includes features such as Enable and Soft Start, allowing for controlled power-up sequences. It operates within an ambient temperature range of -40°C to 85°C. The converter is housed in an 8-pin SO PowerPad package, suitable for surface mount applications.
