RT9284 概述
RT9284 采用TSOT-23-5和TSOT-23-6封装。RT9284 为100Hz~100KHz微控频率升压型白光LED驱动电路，可同时驱动4颗串联白光LED，能完全避免噪音产生。RT9284 在白光LED出现异常情况下，具有过电压保护功能。
The RT9284 /B is a compact, high efficient and high integration LED driver. Internal 22V MOSFET can support 2 to 5 White LEDs for backlighting and camera flashing.Highly integration and internal compensation network minimizes as 5 external component counts. Optimized operation frequency can meet the requirement of small LC filters value and low operation current with high efficiency. The RT9284 Internal soft start function can reduce the inrush current. Tiny package type of TSOT-23-5 and TSOT-23-6 packages provide the best solution for PCB space saving and total BOM cost.
