This circuit is a Mosfet-based linear voltage regulator with a voltage drop of as low as 60mV at 1A. The circuit uses a 15V-0-15V transformer and employs an IRF540 N-channel Mosfet (Q1) to deliver the ...

Milpitas, Calif. — Linear Technology's new LTC4213 electronic circuit breaker senses load currents with the R DS(ON) of an external MOSFET, which eliminates the need for a sense resistor. The company ...

Environmental systems that precipitate dust and carbon particles frequently use high-voltage dc power supplies. However, failure of high-voltage components caused by a change in their properties over ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

LED output is a function of the current through it. So to drive the device, it would seem simple enough to set the LED current with a series power resistor. But there’s a problem with this idea. First ...

The recommended maximum total voltage drop on branch-circuit conductors is ____%. Article 210 outlines the requirements for branch circuits. Branch-circuit rating rules are covered in Part II of this ...

Q: The left taillight on my pickup is somewhat dimmer than the one on the right side. It’s not bad enough to go through the trouble and expense of having fixed it. But it bugs me. Any chance you have ...
