The STI9287C and STI9287CA are boost converters designed for white LED driver with 30V OVP from a single cell Li-ion battery. The STI9287C and STI9287CA use current mode, fixed frequency architecture to regulate LED strings current, which is set with an external current sense resistor. Its low 200mV for STI9287C, 250mV for STI9287CA typical feedback voltage with EN/PWM Pulling High reduces power loss and improves efficiency.

The STI9287C and STI9287CA include 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.
