FEATURES
DESCRIPTION
The LM3445 is an adaptive constant off-time AC/DC
2
Triac Dim Decoder Circuit for LED Dimming
buck (step-down) constant current controller designed
Application Voltage Range 80VAC – 277VAC
to be compatible with triac dimmers. The LM3445
Capable of Controlling LED Currents Greater
provides a constant current for illuminating high
Than 1A
power LEDs and includes a triac dim decoder. The
dim decoder allows wide range LED dimming using
Adjustable Switching Frequency
standard triac dimmers. The high frequency capable
Low Quiescent Current
architecture allows the use of small external passive
Adaptive Programmable Off-Time Allows for
components. The LM3445 includes a bleeder circuit
Constant Ripple Current
to ensure proper triac operation by allowing current
flow while the line voltage is low to enable proper
Thermal Shutdown
firing of the triac. A passive PFC circuit ensures good
No 120Hz Flicker
power factor by drawing current directly from the line
Low Profile 10-Pin VSSOP Package or 14-Pin
for most of the cycle, and provides a constant positive
SOIC
voltage to the buck regulator. Additional features
include thermal shutdown, current limit and VCC
Patent Pending Drive Architecture
under-voltage lockout.
APPLICATIONS
Retro Fit Triac Dimming
Solid State Lighting
Industrial and Commercial Lighting
