National Semiconductor’s LM3445 is a new constant-current controller that enables offline, uniform, flicker-free dimming of high-brightness LEDs with a conventional TRIAC forward or reverse phase-control wall dimmer. The device enables a full 100:1 range of dimming capability and can maintain greater than 1 A of constant current to large strings of LEDs in a variety of residential, architectural, commercial and industrial applications. Offered in a 10-pin mini SOIC package, the LM3445 is an adaptive constant off-time AC-DC buck constant current controller. It includes a bleeder circuit to ensure proper TRIAC operation by allowing current flow while the line voltage is low to enable proper firing of the TRIAC. A passive PFC circuit ensures good power factor by drawing current directly from the line for most of the cycle, and provides a constant positive voltage to the buck regulator.
