The TPS61061DRBR from Texas Instruments is a high-frequency, synchronous boost converter designed for driving white LEDs. It provides a constant current output, making it suitable for applications requiring precise LED current regulation.
Key electrical specifications include an input voltage range of 2.7V to 6V and an output voltage up to 19V. The device features a 400mA internal power MOSFET switch and operates at a fixed 1MHz switching frequency, allowing for the use of small external components. Brightness control is supported via PWM signals on the enable pin or digital control on the ILED pin.
This LED driver is available in an 8-SON (3x3) package, suitable for surface mounting. It also features integrated overvoltage and short-circuit protection for enhanced safety. The TPS61061 is designed for applications such as backlighting in cellular phones, PDAs, and digital still cameras.
