   产品概述 返回TOPPkr嘉泰姆

The CXLE82122 is an adaptive constant off-time AC/DC buck controller for dimmable LED luminaries designed to be compatible with triac dimmers. The CXLE82122 provides a constant current for illuminating high power LEDs and includes a triac dim decoder. The LED brightness is modulated by the scheme of PWM-dimming. The CXLE82122 includes a bleeder circuit to ensure proper triac operation by allowing current flow while the line voltage is low to enable proper firing of the triac. A passive PFC circuit ensures good power factor by drawing current directly from the line for most of the cycle, and provides a constant positive voltage to the buck regulator. Additional features include thermal shutdown, current limit and input supply under-voltage lockout.
