CXLE87179 is a current mode PWM control IC for LED lighting application that operates in constant off-time mode. It integrates a 20V~500VDC linear regulator which allows it to work from a wide range of input voltages without the need for an external low voltage supply. The CXLE87179 supports linear mode dimming with 0V~0.5V variational DC voltage input. The CXLE87179 integrates damper driver for flickless TRIAC mode dimming. It requires only two components (apart from the power stage) to produce a controlled LED current, making it an LED lighting solution for small form factor designs.
