POWER FACTOR CORRECTOR
DESCRIPTION
The UTC
L8562
is a Power Factor Corrector, which can work in
wide input voltage range applications (from 85V ~ 265V) with an
excellent THD. It has very low start up current (about 20 uA) and
a disable function on the ZCD pin, which is designed to keep
lower current consumption in stand by mode.
The device is operating in transition mode, and is able to drive
a Power MOS or IGBT with a ± 400mA current for sourcing and
sinking.
LINEAR INTEGRATED CIRCUIT
