Cxle8323 is an efficient pwm-led constant current driver and control chip with integrated power transistor. The constant current accuracy can reach ?3% of the full voltage range. The chip directly supplies power from the drain input voltage without the auxiliary winding. Cxle8323 is mainly used for the highlighted buck LED drive. The constant output current can be realized without any compensation element. With less peripheral components, the scheme has low cost and LED output short circuit protection characteristics
