ICL9201 是一款低成本的紋波抑制芯片,與LED
燈珠串聯(lián),用來抑制定電流源產(chǎn)生的電流紋波,所需外
圍元器件少、系統(tǒng)成本極低。
ICL9201 在可控硅調(diào)光器調(diào)光全程都能提供優(yōu)異
的去頻閃表現(xiàn)。 iML8686可驅(qū)動高達100mA。用戶可以通過外部電阻將調(diào)節(jié)電流從5mA調(diào)整到100mA。線性過溫保護功能是在芯片的結(jié)溫高于130°C時線性減小電流來保護系統(tǒng)。多個iML8686B芯片可以并聯(lián)連接,以提供更高的驅(qū)動電流能力。該器件采用SOT-89-3L封裝 ICNE2530D is a high voltage linear constantcurrent LED driver for phase–cut dimmable application,which integrates 500V high voltage MOS.The phase-cut dimmer holding current and theLED driving current can be set through the external resistors between 5mA and 100mA, the current precision can reach ±3%.
ICNE2530Dbuilt-innegativetemperaturecompensation function, help to improve the sourceregulation of the linear power supply system. Thebuilt-in negative temperature compensation functioncan effectively prevent damage to the system causedby sudden temperature changes.ICNE2530D system has simple peripherals,flexible application, high reliability, small volume, andlow system BOM cost. It is suitable for all kinds of LEDlamps.
