The TPS61160A/61A is a white LED driver from TI that uses a 2mm x 2mm QFN package and can drive up to 10 LEDs in series. The device has a 2.7V to 18V input voltage range, 26V open LED protection (TPS61160A), 38V open LED protection (TPS61161A), 200mV reference voltage, ±2% accuracy, PWM interface, programmable soft start, up to 90% efficiency, and a 2mm x 2mm x 0.8mm 6-pin QFN package.
The TPS61160A/61A are 2.7 V‑to‑18 V input boost converters designed for white LED backlighting and portable devices. They integrate a 40 V switch FET, PWM dimming interface, soft‑start, and open‑LED protection, delivering up to 90 % efficiency in a 2 mm × 2 mm QFN package.
Typical applications include cellular phones, media players, GPS receivers, and white LED backlighting for displays. The devices support up to 10 LEDs in series (TPS61161A) or 6 LEDs (TPS61160A) and provide a 200 mV reference voltage for current regulation.
