CONTROL CIRCUIT FOR SWITCH MODE POWER SUPPLIES USING MOS  TRANSISTORSDESCRIPTION
The IC TDA4605controls the MOS PowerTransistor and performs all necessary regulation and

monitoring functions in free running flyback converters.

Since good load regulation over a wide load range is attained, this IC is particularly suitable

for Consumer as well asIndustrial PowerSupplies.

Alternative source of theTDA4605 is alsoavail-

ablefrom SIEMENS semiconductors Consumer ElectronicsA.G.

N - CHANNEL 400V - 0.48 Ω - 10 A - TO-220
PowerMESH MOSFET

This power MOSFET is designed using the company’s consolidated strip layout-based MESH OVERLAY process. This technology matches and improves the performances compared with standard parts from various sources.

APPLICATIONS
# HIGH CURRENT SWITCHING
# UNINTERRUPTIBLE POWER SUPPLY (UPS
# DC/DC COVERTERS FOR TELECOM,
# INDUSTRIAL, AND LIGHTING EQUIPMENT
