MT9284 SOT-23-6 High-Efficiency LED Driver IC 1.2MHz b11g8 XI'AN Aerosemi Tech MT9284-28J

Product Overview: The MT9284 is a high-efficiency step-up (boost) converter designed for driving up to 7 series white LEDs (WLEDs) from a single-cell Lithium-Ion battery. It utilizes current-mode, fixed-frequency architecture to regulate LED current, which is measured via an external current sense resistor, and includes integrated protections such as under-voltage lockout (UVLO), current limiting, and thermal overload protection.
