IRS2538DSPBF Description
This IC takes full advantage of IR’s patented ballast and high-voltage technologies to realize a simple, highperformance 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 halfbridge voltage to perform necessary protection...
