产品概述 返回TOPK6U嘉泰姆

The CXLE81112/CXLE81112A is current mode DC/DC controller that drives up to four strings connected in parallel configuration with multiple LEDs in each string connected in series. External current sense resistor and slope compensation resistor make it flexible for various applications. A PWM dimming input controls a duty ratio from 0% to 100% with frequency up to few kilohertz. The CXLE81112/CXLE81112A includes hiccup protection from both short and open circuits, with automatic recovery after the fault condition is cleared. The CXLE81112 is available in a TQFN4X4-24 package. The CXLE81112A is available in a TQFN4X4-28 and SOP-28 package.
