The STI9287B is a step-up converter designed for driving up to 7 series white LED's from a single cell Lithium Ion battery. The STI9287B uses current mode, fixed frequency architecture to regulate an LED current, which is measured through an external current sense resistor. Its low 202mV typical feedback voltage with EN/PWM Pulling High reduces power loss and improves efficiency.

The STI9287B includes under-voltage lockout, current limiting and thermal overload protection preventing damage in the event of an output overload.

Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. Internal soft start function can reduce the inrush current. SOT23-6 package type provides the best solution for PCB space saving and total BOM cost.

  • PDA LED Back light

  • Digital Still Cameras

  • Camcorder
