The CXLE8450 series are off-line controller ICs for LED lighting. Through optimization of the external components, these ICs can be made to operate in a range from 85VAC to 270VAC, as well as by DC input, and a diversity of specifications can be achieved by selecting components appropriate for the circuit configuration. Fixed off-time control is used for the basic control method, and by detecting the current that flows to the external power MOSFET, the current that flows to the LED is monitored to provide a stable power supply for LED lighting. Three product series differing by function type are available, the CXLE8450A type, CXLE8450B type and the CXLE8450C type. The circuit configuration of type A is designed for the power factor, achieving a high power factor by synchronizing the LED current to the input current (sine wave). Type B and C holds the peak current due to switching that flows to the external power MOSFET constant, enabling the LED current to be kept constant. With the type C, dimming is possible by inputting a PWM signal into the EN/DIM pin to set the LED current within a range of 1% to 100%.
