XT410X is a family of highly integrated Constant
Current LED power switch. The IC utilizes
Quasi-Resonant (QR) Buck topology with active
PFC control for high PF, low THD, and high
efficiency.
XT410X integrates internal demagnetization
detection circuit and 650V/600V power MOSFET
with high voltage startup, which eliminates
auxiliary winding for power supply and
demagnetization and simplifies the design and
production cost of the system. Additionally, the
system surge performance is also optimized in
XT410X to pass 2.5kV surge level with minimum
system cost. The IC adopts accurate current
sensing, close loop constant current control to
achieve high precision CC control with excellent
line and load regulation.
XT410X integrates functions and protections of
Cycle-by-cycle Current Limiting (OCP), Thermal
Fold-back (OTP), Line OVP, Output Over Voltage
Protection (OVP), LED Open/Short Protection, etc.
