3 Description
The TPS92560 is a simple LED driver designed to
drive high-power LEDs by drawing constant current
from the power source. The device is ideal for MR16
and AR111 applications, which require good
compatibility to DC and AC voltages and electronic
transformers. The hysteretic control scheme does not
need control loop compensation while providing the
benefits of fast transient response and high power
factor. The patent pending feedback control method
allows the output power to be determined by the
number of LED used without component change. The
TPS92560 supports both boost and SEPIC
configurations for the use of different LED modules.
