Commonly used 3-pin linear voltage regulators, for example the LM317, cannot handle input voltages in excess of about 30V. The LR8A from Supertex Inc is a new, adjustable three pin regulator that can ...

The switching power supply inFigure 1 produces 3.3V dc froman input voltage of 2.5 to 20V dc withhigh efficiency. The circuit operates atan input voltage as low as 1.5V once itstarts from a minimum of ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

Some applications require a positive voltage to be generated from a negative input voltage. This can be done either by using a transformer based topology, such as a flyback converter, or with a ...

Input protection for switched mode inverters and converters affects an increasing number of sectors, writes Martin Keenan of Avnet Abacus. Switched mode inverters and converters form the heart of many ...

The LTC4418 is a dual input power prioritizer for 2.5V to 40V systems. To enable portability, preserve memory during brownouts, and ensure a graceful shutdown on power loss, electronic systems employ ...
