Flyback BASICS

Flyback operation will be illustrated with reference to the basic circuit and the waveforms of fig. 1. It is a two step process. During the ON-time of the switch, energy is taken from the input and stored in the primary winding of the Flyback TRANSFORMER (actually, two coupled inductors). At the secondary side, the catch diode is reverse biased, thus the load is being supplied by the energy stored in the output bulk capacitor.

Компоненты Описание : Control IC for Switched Mode Power Supplies using MOS Transistors

The IC ILA 4605-2 controls the MOS - power transistor and performs all necessary regulation and monitoring function in free running Flyback converters. Because of the fact that a wide load range is achieved, this IC is applicable for consumer as well as industrial power supplies.
The serial circuit and primary winding of the Flyback TRANSFORMER are connected in series to the input voltage. During the switch - on period of the transistor, energy is stored in the TRANSFORMER. During the switch - off period the energy is fed to the load via the secondary winding. By varying switch - on time of the Power transistor, the IC controls each portion of energy transferred to the secondary side such that the output voltage remains nearly independent of load variations. The required control information is taken from the input voltage during the switch - on period and from a regulation winding during the switch - off period. A new cycle will start if the TRANSFORMER has transferred the stored energy completely into the load.

FEATURES:
• Fold - back characteristics provides overload protection for external components
• Burst operation under secondary short - circuit condition implemented
• Protection against open or short of the control loop
• Switch - off if line voltage is too low (undervoltage switch - off)
• Line voltage depending compensation of fold - back point
• Soft start for quiet start - up without noise generated by the TRANSFORMER
• Chip - over temperature protection (thermal shutdown)
• On - chip ringing suppression circuit against parasitic oscillations of the TRANSFORMER

The IC TDA 4605-3 controls the MOS-power transistor and performs all necessary control and protection functions in free running Flyback converters. Because of the fact that a wide load range is achieved, this IC is applicable for consumer as well as industrial power supplies.
The serial circuit and primary winding of the Flyback TRANSFORMER are connected in series to the input voltage. During the switch-on period of the transistor, energy is stored in the TRANSFORMER. During the switch-off period the energy is fed to the load via the secondary winding.
