How does a fuse work?
The fuse breaks the circuit if a fault in an appliance causes too much current to flow. This protects the wiring and the appliance if something goes wrong. The fuse contains a piece of wire that melts easily. If the current going through the fuse is too great, the wire heats up until it melts and breaks the circuit.
What is non isolated buck converter?
The buck converter is a step-down converter that performs rectifying by means of a diode; it is a representative system used in non-isolated step-down switching DC/DC converters. In applications where isolated is not needed, this system, which does not use a transformer, provides a simple solution.
What do you need to know about a buck converter?
A buck converter, or DC-DC step-down switching regulator, is a type of DC-DC converter which provides an output regulated voltage that is lower than its input voltage. Monolithic buck converter ICs for any application requirement.
Why are isolated power converters more expensive than non isolated?
Isolated converters tend to be more expensive than non-isolated. A major contributor to the cost difference is the use of a transformer in place of an inductor. Transformers tend to be custom built as opposed to the inductor in a non-isolated converter which can be purchased off the shelf.
What can a low IQ buck converter do?
ST’s low IQ buck converters are ideal for any power-budgeted applications, such as battery-powered devices or green-compliant equipment with long stand-by operation. Extend the battery life and reduce the overall power consumption of your industrial and automotive application designs.
When do you need an isolated power supply?
There are several cases where an isolated power supply may be required or provide some benefit in an application. These include safety compliance, the breaking of ground loops, and level shifting. Safety requirements are a common reason to use an isolated power converter.
