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.
