Applications
Typical applications are capacitive discharge systems for
strobe lights, nailers, staplers and gas engine ignition. Also
controls for power tools, home/brown goods and white
goods appliances.
Internally constructed isolated packages are offered for
ease of heat sinking with highest isolation voltage.
