TPS55340QRTERQ1 Description

Short technical summary and product information.

The Texas Instruments TPS55340QRTERQ1 is an integrated, 5-A, 40-V wide input range boost, SEPIC, or flyback DC/DC converter. It is qualified for automotive applications and meets AEC-Q100 standards.

 

This device operates with an input voltage range from 2.9 V to 38 V and features an adjustable output. The switch current limit is typically 6.6 A, with the device itself rated for 5.25 A. It supports various topologies including Boost, Flyback, Forward, and SEPIC, and operates as a nonsynchronous rectifier.

 

The TPS55340QRTERQ1 is available in a 16-WQFN (3x3 mm) package with a PowerPad for enhanced thermal performance. It is designed for surface mounting and operates within a temperature range of -40°C to 125°C (TA).

 

Key features include frequency synchronization, light load efficiency, and adjustable soft-start time. Protection mechanisms include cycle-by-cycle current-limit, thermal shutdown, and UVLO.
