DESCRIPTION
The ICTDA4605controls theMOSPowerTransis-
tor and performs all necessary regulation and
monitoring functions in free running flyback con-
verters. Since good load regulation over a wide
load rangeisattained,thisICis particularlysuitable
for Consumeraswell asIndustrialPowerSupplies.
Alternative source of the TDA4605is also avail-
able from SIEMENS Semiconductors Consumer
