The Texas Instruments TPS61058DRCR is a high-power white LED driver IC featuring a synchronous boost DC-DC converter with integrated down conversion mode. It is optimized for driving single-cell white LEDs up to 800mA from a 2.7V to 5.5V input. The device operates at a fixed frequency of 650 kHz (typical) and utilizes pulse-width modulation (PWM) control with a synchronous rectifier for maximum efficiency.
The TPS61058DRCR offers features such as LED disconnect during shutdown, open/shorted LED protection, and over-temperature protection. It has a low shutdown current of 100 nA (typical). The device is packaged in a compact 3mm x 3mm 10-pin QFN PowerPAD package (10-VSON).
This LED driver is suitable for applications like torch and camera flash supplies for cell phones, smart-phones, and PDAs. The total solution size can be less than 80 mm².
