The TPS61080/1 is a high-integration DC/DC boost converter from TI, with a 2.5-V to 6-V input voltage range, up to 27-V output voltage, a 0.5-A/1.3-A integrated switch and an integrated power diode. It also has short circuit protection, overvoltage protection, overcurrent protection and undervoltage protection.
The document describes the TPS61080 and TPS61081 boost regulators, which integrate a power switch, isolation switch, and diode. It lists key features such as a 2.5‑V to 6‑V input range, up to 27‑V output, selectable 1.2 MHz/600 kHz switching frequency, and up to 87% efficiency. Typical applications include LED backlights, OLED power supplies, xDSL, and flash‑light drivers.
Electrical characteristics, pin functions, absolute maximum ratings, and recommended operating conditions are detailed, along with layout guidelines, land‑pattern drawings, and safety notices. Graphs of efficiency, regulation, and transient response illustrate performance across load and voltage conditions.
