This document is an engineering report of a universal input 12W 5V off-line flyback converter power supply utilizing F3R80 CoolSET™ICE3AR4780VJZ. The application evaluation board is operated in Discontinuous Conduction Mode (DCM) and is running at 100 kHz switching frequency. It has a si...
This is due to the continuous nonswitching behavior of the two currents. A flyback converter has both discontinuous input and output currents which makes it 3511fc LT3511 APPLICATIONS INFORMATION similar to a nonisolated buck-boost. The duty cycle will affect the input and output currents, ...
In the flyback converter, different snubber structures can be applied and each of the structure has its advantage and disadvantage.The demand having a snubber circuit in the power supply topology leads to specific verification methods during the design to obtain a proper and reliable design. These...
The commonly supported configurations include Boost, Flyback and SEPIC topologies. This report focuses on designing the LM5157x/LM5158x as a primary side regulated (PSR) flyback converter. The design procedure is generic on selecting suitable components of the PSR flyback converter for the given ...

In the flyback converter of Figure 1d, the bias supply is proportional to VIN and VOUT. However, in the forward converter, L1's presence decouples the bias supply from VOUT. In Figure 3a, the bias supply equals (VIN • N – VF). In Figure 3b, the bias supply equals (VIN • N1...
Two different cases can occur based on whether or not the converter internal supply is used. The SMPS converter IC uses its internal supply As the supply converter already features the supply for its internal MOS (the source of which is connect...
