flicker-free brightness control in any

wide-range dimming application.

dimming input that permits brightness

control from an external potentiometer,

DC voltage source, or PWM signal. The

resultant “burst drive” that energizes the

lamp was designed specifically to ensure

that no premature lamp degradation

occurs.

design is based on a new Direct Drive

topology, which provides a number of

cost and performance advantages.

this new topology are fixed-frequency

operation and secondary-side strike-
