STK4046XI
Features
• Compact packaging supports slimmer set designs
• Series designed from 50 up to 150 W and pincompatibility
• Simpler heat sink design facilitates thermal design of
slim stereo sets
• Current mirror circuit, cascade circuit and purecomplimentary circuit application reduce distortion to
0.008 %
• Supports addition of electronic circuits for thermal
shutdown and load-short protection circuit as well as
pop noise muting which occurs when the power supply
switch is turned on and off.
