General Description<\/h3>\n\n\n\n

The EC4213 is a constant N-channel MOSFET current linear LED controller for replace discrete solutions in AC\/DC power application (up to 270VAC). The controller can drive an output power of \u00b110% variation from a universal input voltage range of 120VAC\u00b116%, or 230VAC\u00b116% for different LED strings.<\/p>\n\n\n\n

The solution eliminates the need of individual components by combining them into a single package, which results in a significant reduction of both system cost and board space.<\/p>\n\n\n\n

The controller is capable of a dimming input for adjustable LED brightness control by Pulse Width Modulation (PWM).<\/p>\n\n\n\n

The EC4213 can protect the external N-channel MOSFET against over temperature and over current.<\/p>\n\n\n\n

Internal thermal foldback function regulates LED driving current automatically for temperature management of the LEDs or the N-channel MOSFET during high power operation or high ambient temperature conditions by an external NTC resistor. These features provide maximum system protection for the demanding lighting applications.<\/p>\n\n\n\n

The EC4213 is available in a space saving SOP10 package, and the operating temperature is from \u201340\u00b0C to +125\u00b0C.<\/p>\n\n\n\n
