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.
