DESCRIPTION
The FT8260/1/2x is a single stage
primary-side-control offline LED controller with high
power factor, low THD and excellent current
accuracy for isolated LED lighting applications.
The accurate current control from the primary side
significantly simplifies the LED lighting system
design by eliminating the secondary side feedback
components and the opto-coupler.
The extremely low start-up current and quiescent
current of FT8260/1/2x reduce the power
consumption, resulting in excellent efficiency.
The multi-protection function of the FT8260/1/2x
greatly enhances the system reliability and safety.
The FT8260/1/2x features fruitful protection
functions such as over-voltage protection,
short-circuit protection, cycle-by-cycle current limit,
over-temperature protection, VCC UVLO protection.
