線性降壓恒流

TX6411 是一種低靜態(tài)電流、帶 PWM 調(diào)光功能的線性降壓 LED 恒流驅(qū)動(dòng)器，僅需外接一個(gè)電阻和一個(gè) NMOS 管就可以構(gòu)成一個(gè)完整的 LED 恒流驅(qū)動(dòng)電路，調(diào)節(jié)該外接電阻就可以調(diào)節(jié)輸出電流，輸出電流可調(diào)范圍為 10mA到 3000mA。內(nèi)置過熱保護(hù)功能，可有效保護(hù)芯片及 MOS 管， 避免因過熱而造成損壞。 具有很低的靜態(tài)電流，典型值為 49uA。帶 PWM 調(diào)光功能，可通過在DIM 腳加 PWM信號(hào)調(diào)節(jié) LED 電流。芯片采用 SOT89-5 和 SOT23-5 封裝\n
