The TPS61301YFFT from Texas Instruments is a multiple LED camera flash driver with an I2C compatible interface and hardware reset input. It utilizes a high-frequency synchronous boost topology to drive up to three white LEDs in parallel, providing 400-mA, 800-mA, and 400-mA maximum flash current respectively. An extended high-current mode allows for up to 1025-mA, 2050-mA, and 1025-mA flash current from a storage capacitor, minimizing peak battery current demand.
This device operates as a regulated current source and a standard voltage boost regulator, maintaining output voltage regulation even when the input voltage exceeds the nominal output. It features a power-save mode for improved efficiency at low output power, achieving up to 95% efficiency. The 2-MHz switching frequency enables the use of small, low-profile inductors. The TPS61301YFFT is available in a 20-pin DSBGA package and operates within a temperature range of -40°C to 85°C.
Key features include an I2C compatible interface supporting up to 3.4 Mbits/s, hardware voltage mode selection, and a hardware reset input. The total solution size is less than 25 mm² with a height of less than 1 mm, making it suitable for compact designs. It also includes features like automatic V F and ESR calibration, and an integrated LED safety timer.
