By jd john morris download pdf the lt3748 is a switching regulator controller specifically designed to simplify the design of isolated power supplies using a flyback topology.
Isolated power supply design.
Pcb layout considerations for an isolated power supply design.
This means that power and voltage is transferred from the input to the output without a direct electrical connection between the two sections.
The use of a transformer in an isolated power supply will protect users from electrical shock.
Isolated power supplies are routinely utilized in industrial consumer and telecom applications concerned with the protection of sensitive loads and the long term reliability of the equipment.
Transformer drivers with external transformers can provide a simple isolated power solution.
When you are laying out an isolated power supply on your printed circuit board you are going to have to accept the fact that you are going to be working with some larger components.
Isolated power supplies made easy.
No third winding or opto isolator is required as the lt3748 senses the isolated output voltage directly from the primary side flyback waveform.
Although an isolated power supply is more complex than a non isolated power supply it must still fit into a small space and perform with high efficiency.
Our portfolio of isolated bias supplies and modules and isolated power converters are comprised of high density integrated fet converters and integrated transformer modules to reduce your power supply bom count and simplify your isolated dc dc design.
