Texas Instruments TPS61160/TPS61161 LED Driver Datasheet
The TPS61160 and TPS61161 are high‑efficiency white LED boost converters offered in a compact 2 mm × 2 mm QFN package. They support an input voltage range of 2.7 V to 18 V and can drive up to ten LEDs in series, providing up to 90 % conversion efficiency. Brightness can be adjusted via a 1‑wire digital EasyScale interface or a PWM signal on the CTRL pin, and the devices include built‑in soft‑start and open‑LED protection.
The datasheet provides full electrical characteristics, absolute maximum ratings, recommended operating conditions, and layout guidelines. Key parameters such as switching frequency (600 kHz), open‑LED protection thresholds (26 V for TPS61160, 38 V for TPS61161), and thermal shutdown specifications are listed, along with typical application circuits and land‑pattern drawings for PCB design.
