RT9284A/B/C
Tiny Package, High Performance, Constant Current Switching Regulator for White LED
General Description
Features
The RT9284A/B/C is a compact, high efficient and high integration LED driver. Internal 20V MOSFET can support 2 to 4 White LEDs for backlighting and camera flashing.
Highly integration and internal compensation network minimizes as 5 external component counts. Tiny package type of TSOT-23 package provide the best solution for PCB space saving and total BOM cost.
Internal 0.1V low current feedback voltage, which minimize the power loss due to the current sense resistor. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency, as one of the LED is open.
