   产品概述 返回TOPqK0嘉泰姆

The CXLE8652 is a 2-channel LED driver, designed for current regulation. It may be used in various current regulation circuits, especially suitable for LED applications. It lets LEDs work under stable current and avoid brightness unstable caused by current change, while its low voltage can reduce power consumption. The connection of the VDD power pin may also be used for brightness control of LEDs via PWM signals; therefore suitable for applications that need brightness adjustment. The connection of REXT pin can be used for the control of output current, to control and drive more LEDs. When REXT is open, VCH1, VCH2 pins may provide 30mA of current. To achieve operations with VCH1/VCH2 current over 60mA, connect the ICs in parallel.
