Cxle83162a cxle83162b realizes various protection functions at the same time, including OCP, SCP, OVP and OTP to ensure the reliable operation of the system. The critical conduction mode ensures that the cxle83162a cxle83162b can control the power switch to open when the inductive current is zero, reduces the switching loss of the power tube, and ensures that the system has a peak efficiency of more than 95%. The critical conduction mode with zero inductance current Valley and the peak inductance current compensated by the input bus voltage ensure the high accuracy of the output LED current and good linear and load regulation. It is not sensitive to the change of inductance. I-type inductance can be used. The chip is equipped with high voltage power MOS tube, the peripheral circuit is simple, and the system cost is low. Cxle83162a cxle83162b is a high-precision LED constant current control chip, which works in zero current on and peak current off critical conduction mode. It is mainly used in non isolated step-down LED power supply system.
