Cxle8354d is a high efficiency non isolated step-down LED constant current driver chip which is suitable for the non isolated step-down LED constant current driver power supply of 85vac~265vac

The cxle8354d integrates high-precision current detection and constant current drive circuit, which can achieve high-precision LED constant current output and excellent line voltage regulation. At the same time, cxle8354d works in the inductive current critical mode of peak current off and zero current on. The LED output current does not change with the change of inductance and LED output voltage, so it has the advantages of excellent load adjustment rate and insensitive to the change of inductance
