G5345 Datasheet (Global Mixed-mode Technology) - Triac Dimmable Offline LED Driver

G5345, Triac Dimmable Offline LED Driver

The G5345 is an adaptive constant off-time AC/DC buck controller for dimmable LED luminaries designed to be compatible with triac dimmers.

The G5345 provides a constant current for illuminating high power LEDs and includes a triac dim decoder.

The LED brightness is modulated by the scheme of PWM-dim
