CXLE 86202 is a linear LED constant current driver chip with high efficiency and support SCR dimming. CXLE86202 support leading/trailing edge dimmer output current with high accuracy and no EMI issues. The peripheral circuit of CXLE 86202 is very simple, and the output current can be flexibly set by the external resistor RSET, which can be widely used in all kinds of light sources and lamps with high power factor of commercial power input.
CXLE 86202 built-in efficiency improvement circuit, through the control algorithm, to achieve a good thyristor dimmer compatibility, and can achieve 84% system efficiency. Built-in linear compensation circuit, the output current has a good linear adjustment rate, and the CXLE 86202 has an external expansion chip (CXLE86203) drive port, which can be configured with an external expansion chip to increase the power supported by a single chip.
CXLE86202 built-in overtemperature adjustment function. When the chip temperature is too high, the output current is automatically reduced to improve the reliability of the system.
The CXLE 86202 system does not require magnetic components such as inductors or transformers, the system structure is simple, the peripheral components are very few, and the cost of the solution is very low.
