Cxle8322 is a pwm-led constant current driver and control chip with internal integrated power tube and high efficiency. The constant current accuracy can reach ?3% of the full voltage range. The chip directly supplies power from the drain input voltage without auxiliary winding. Cxle8322 is mainly applicable to the highlighted buck LED driver. Without any compensation element, the constant output current can be achieved. With less peripheral components and low cost, it has the characteristics of LED output short circuit protection and over temperature protection.
