   The CXLE8292 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the LED voltage. The CXLE8292 device operates from an input supply between 6V and 40V and provides an externally adjustable output current of up to 1A. Depending upon supply voltage and external components, this can provide up to 30 watts of output power.The 1 includes the output switch and a high-side output current sensing circuit, which uses an external resistor to set the nominal average output current.Output current can be adjusted below the set value, by applying an external control signal to the VSET pin. The VSET pin will accept either a DC voltage or a PWM waveform.The soft-start time can be increased using an external capacitor from the VSET pin to round.Applying a voltage of 0.2V or lower to the VSET pin turns the output off and switches the device into a low current standby state. UaG嘉泰姆
CXLE8292是一款连续工作模式下的降压转换器，专为单只或多只大功率LED，内置高精度电流检测器，能通过外置电阻设定输出电流，可选择软开关---开关式1A恒流芯片，软启动、高达1.5Mhz开关频率，开路保护，从6~40V输入，最大电流可以做到1A电流，恒流输出精度2%，效率高达97%以上。
