The TPS61235PRWLT: The internal switch is rated for 6.5 A, which sets the output current ceiling: at 5.1 V, the maximum continuous output current is roughly 4.5 A from a 3.6 V input, assuming 90% efficiency. That is enough to power a USB-C sink at 5 V / 3 A with margin, or a 5 V sensor array drawing 2 A. Synchronous rectification replaces the external Schottky diode with a second internal FET, which cuts conduction loss at high output currents and improves efficiency above 90% across most of the load range.
Package and board-fit for space-constrained designs
The device is housed in a 9-VFQFN package with the supplier device code 9-VQFN-HR (2.5x2.5 mm). The small footprint suits handheld, IoT, and portable equipment where board area is at a premium.
Active lifecycle and compliance — no obsolescence risk
Texas Instruments provides the datasheet, application notes, and design tools for the TPS61235 family. The base product number TPS61235 covers multiple output voltage options and package variants; the PRWLT suffix identifies this specific fixed 5.1 V output in the 9-VQFN-HR package.
