TPS92560
SNVS900B –DECEMBER 2012–REVISED DECEMBER 2015
TPS92560 Simple Led Driver for MR16 and AR111 Applications
1 Features 3 Description
The TPS92560 is a simple LED driver designed to
1
• Controlled peak input current to prevent over-
drive high-power LEDs by drawing constant current
stressing of the electronic transformer
from the power source. The device is ideal for MR16
• Allows Either Step-Up or Step-Up/Down Operation
and AR111 applications, which require good
• Compatible to Generic Electronic Transformers
compatibility to DC and AC voltages and electronic
transformers. The hysteretic control scheme does not
• Compatible to Magnetic Transformers and DC
need control loop compensation while providing the

benefits of fast transient response and high power
• Integrated Active Low-Side Input Rectifiers
factor. The patent pending feedback control method
• Compact and Simple Circuit
allows the output power to be determined by the
number of LED used without component change. The
