Cxle83166 has wide working voltage suitable for full range AC input voltage or 12V~500V DC voltage input various protection functions at the same time, including OCP SCP OVP and OTR

Cxle83166 has wide working voltage, suitable for full range AC input voltage or 12V ~ 500V DC voltage input. Cxle83166 has realized various protection functions at the same time, including OCP, SCP, OVP and OTR, etc., to ensure the system can work reliably in the critical conduction mode with zero inductance current valley value combined with input The peak inductance current after the bus voltage compensation ensures the high accuracy of the output LED current of cxle83166, and has excellent linear adjustment rate and load adjustment rate. I-type inductance can be used and is not sensitive to the change of inductance. Cxle83166 is a high-precision LED constant current driver chip working in zero current on and peak current off critical conduction mode. It is mainly used in non isolated step-down LED power supply system and supports PWM / analog level dimming. The critical conduction mode ensures that the cxle83166 switches on when the inductive current is zero, reduces the switching loss of the power transistor, and ensures that the system has a peak efficiency of more than 93%
