QX6102
Built-in NPN Buck Type CC LED Driver
General Description
QX6102 is a built-in NPN Buck type constant-current LED driver with high precision and self-powered. It is suited AC 85V~265V non-isolated LED driver supply.
QX6102 uses self-powered structure, and need no auxiliary winding, with built-in NPN, which can improve cost performance.
QX6102 adopts patented high end current detect, fixed frequency, current mode PWM control techniques, and has excellent line regulation and load regulation.
QX6102 has frequency shuffling function which can improve EMI performance. With internal loop and slope compensation, QX6102 needs no external compensation, which makes the application design easier.
QX6102 has several protect functions, including LED open/short protect, OCP, UVLO, OVP, power clamp and so on.
