DIP8
(Plastic Package)
ORDER CODE : TDA4605
DESCRIPTION
The IC TDA4605 controls the MOS Power Transis-
tor and performs all necessary regulation and
monitoring functions in free running flyback con-
verters. Since good load regulation over a wide
load range is attained, this IC is particularly suitable
for Consumer as well as Industrial Power Supplies.
Alternative source of the TDA4605 is also avail-
able from SIEMENS Semiconductors Consumer
