PIN CONNECTION ( top wiew )

signed to work with a single sense resistor. Dur-

ing chopping t(OFF) time the current is reduced

by half, improving efficiency. Higher current appli-

cations can be achieved by paralleling two L6223.

The L6223 is mounted in a 20-lead Powerdip

package, (16+2+2). Four ground leads conduct

heat to dedicated heatsink area on the PCB.
