MT9284BS6 1.2MHz, High Efficiency Boost White LED Driver SOT23-6

The MT9284BS6 is a step-up converter designed for driving up to 7 series white LEDs from a single cell Lithium Ion battery. The MT9284 uses current mode, fixed frequency architecture to regulate an LED current, which is measured through an external current sense resistor. 

The MT9284BS6 includes 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. Tiny package type provides the best solution for PCB space saving and total BOM cost.
