Cxle8354c cxle8354b cxle8354a 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

The cxle8354c cxle8354b cxle8354a integrates high-precision current detection and constant current drive circuit inside, which can achieve high-precision LED constant current output and excellent line voltage regulation rate. At the same time, cxle8354c cxle8354b cxle8354a works in the inductive current critical mode of peak current off and zero current on, and the LED output current does not vary with the inductance and LED output voltage
It has the advantages of excellent load regulation and insensitivity to the change of inductance.
Cxle8354c cxle8354b cxle8354a is internally integrated with 500V power tube, and adopts the source drive mode. The working current of the chip is very low, without auxiliary winding detection and power supply, without any compensation elements, only a few peripheral elements, it can achieve high efficiency LED constant current output, greatly saving the cost and volume of the system.

Cxle8354c cxle8354b cxle8354a 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
