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 undervoltage 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.
