TDA4605 Control IC for Switched-Mode Power Supplies using MOS-Transistors

Application Circuit Application circuit shows a flyback converter for video recorders with a power rating of 50 W. The circuit is designed as a wide-range power supply tor AC-line voltages ot 90 to 270 V. The AC-input voltage is rectified by bridge rectifier GR1 and smoothed by C1 . The NTC limits t.
