Isolated Power Supply Design

The use of a transformer in an isolated power supply will protect users from electrical shock.
Isolated power supply design. 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. 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. An isolated power supply is a power supply that is electrically isolated from the rest of the circuit that it is powering often by an isolation transformer. No third winding or opto isolator is required as the lt3748 senses the isolated output voltage directly from the primary side flyback waveform.
Such a supply is useful for testing circuits devices such that they re isolated as the name of course suggests. 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. Pcb layout considerations for an isolated power supply design. Isolated power supply design some considerations one piece of equipment that the lab has been lacking is an isolated power supply.
Transformer drivers with external transformers can provide a simple isolated power solution. Isolated power supplies made easy.
