The STI9287C and STI9287CA are boost converters designed for white LED dꦬriver with 30V OVP from a single cell Li-ion batteryꦜ. The STI9287C and STI9287CA use current mode, f🤡ixed freq☂uency architecture to regulate LED strings curre🍷♈nt, 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 lock🌞out, current limiting and thermal overload protection𝐆 preventing damage in the event of an output overload. Optimized operation frequency can meet the requirement of small LC fi🦋lters value and low operation current with high efficiency. Interna🌄l soft start function𓆉 can reduce the inrush current. SOT23-6 package type provides the best soluti🅰on &🌳nbsp;for PCB space saving and total BOM cost.
