Linear LED Driver
(Preliminary Version)
EC4219
Description：
EC4219 是一顆 Single channel Linear LED Constant current driver。可由外接電阻調整輸出電流，恒定電流精
度高；輸出電流不隨輸出電壓變化而變化。
Feature：
●可調式輸出電流 5mA-60mA
●恒定電流精度±3%
●過溫保護
●晶片可與 LED 共用 PCB 板
● SOP-8(EP) 和 TO252 封裝
Application
● LED 球泡燈
● LED 燈管、吸頂燈
ABSOLUTE MAXIMUM RATINGS
● Out vs GND：-0.3V~+450V
● Cs vs GND：-0.3V~+9V
● Operating Temperature Range：-20℃~+125℃
● Junction Temperature Range：-40℃~+150℃
● Storage Temperature Range：-60℃~+150℃
● E.S.D(Human Body Mode)：2KV
● E.S.D(Machine Mode)：200V
Note:
Absolute Maximum Ratings are those values beyond which damage to the device may occur. Functional
Operation under these conditions is not implied. Continuous operation of the device at the absolute rating level
may affect device reliability.
