|ISSI Expands LED Driver Family With AC/DC LED Driver IC for General Lighting Applications|
The IS31LT3916 is a fixed-frequency, peak current mode controller designed to deliver highly accurate current regulation at a constant power to the LED load. Designs utilizing this device will maintain current accuracy without any type of secondary side feedback such as an opto-coupler while being insensitive to external component tolerances. The device has an automatic correction for peak current threshold that keeps the current constant with varying line voltage while maintaining high power factor. In addition, the IS31LT3916 LED driver incorporates many features such as soft-start, Vcc undervoltage lockout with hysteresis, and protections against output over-voltage, output open and short circuit, primary side over-current and thermal shutdown with hysteresis enabling a robust and reliable system solution.
Industry analysts expect 2013 to be a pivotal year as LED lighting adoption gains momentum in general lighting applications. With environmental regulations worldwide limiting high power incandescent use, LEDs offer an alternative solution which is becoming attractive as SSL solution costs decline rapidly. ISSI continues to expand its LED Driver offerings with innovative and cost effective solutions to address the gamut of indoor and outdoor lighting applications. "IS31LT3916 extends our LED Driver offering for general lighting applications," remarked
