Product details

Automotive-grade multi-topology regulator

The TPS61175QPWPRQ1 from Texas Instruments is an automotive AEC-Q100 qualified DC-DC converter supporting boost, flyback, and SEPIC topologies with a single adjustable output. It operates from a 2.9V to 18V input rail and can deliver up to 38V output through an integrated 3A switch.

Thermal and temperature-grade fit

The 14-HTSSOP package with exposed pad improves thermal dissipation compared to a standard TSSOP, which matters when the 3A switch is running near its current limit at elevated ambient.

It is the Q-grade (automotive) variant of the base TPS61175, and the 'Q' suffix indicates AEC-Q100 qualification and PPAP documentation available through the supply chain.

Frequently asked questions

How can I order the TPS61175QPWPRQ1 or request a quote?

Submit an RFQ through this page with your target quantity and target price. We confirm current pricing and lead time at quote. The part is Active and in our sourcing network; we do not show live stock on the public page, but we respond to every RFQ with availability and a firm quote.

Is the TPS61175QPWPRQ1 AEC-Q100 qualified?

Yes, it is listed under the Automotive, AEC-Q100 series. The 'Q' in the order code and the series designation confirm AEC-Q100 qualification.

Can the TPS61175QPWPRQ1 be used in flyback or SEPIC topologies?

Yes, the device supports boost, flyback, and SEPIC topologies. The adjustable output and wide input range make it suitable for isolated flyback designs and SEPIC converters where the output voltage can be above, below, or equal to the input.
