MT9201 SOT-23-6 High-Efficiency LED Driver IC 1.2MHz b9hb XI'AN Aerosemi Tech MT9201

Product Overview: The MT9201 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 a current-mode, fixed-frequency architecture to regulate LED current, measured through an external sense resistor, and features a low 200mV feedback voltage to reduce power loss and improve overall system efficiency.
