Features

• Compact packaging supports slimmer set designs

• Series designed from 20 up to 100 W (200 W) and pin-

compatibility (120 to 200 W have 18 pins)

• Simpler heat sink design facilitates thermal design of

slim stereo sets

• Current mirror circuit application reduce distortion to

0.08 %

• 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.
