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
L6223A. The L6223A is mounted in a 20-lead
Powerdip package, (16+2+2). Four ground leads
conduct heat to dedicated heatsink area on the
PCB.
