Magnetic Replacement Ballast IC

Features

Description

This IC takes full advantage of IR’s patented ballast

and high-voltage technologies to realize a simple, high-

performance magnetic ballast replacement solution.

The IC includes a novel single-stage circuit topology

and control method to achieve high power factor and

low THD without a PFC stage or any electrolytic

capacitors. A single high-voltage pin senses the half-

bridge voltage to perform necessary protection

functions. Closed-loop control of the lamp current

provides constant lamp brightness over a wide line input

voltage range. Combining these high-voltage control

algorithms in a single 8-pin IC results in a large

reduction in component count, an increase in

manufacturability and reliability, a reduced design cycle

Ballast control plus half-bridge driver in one IC
