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 ...

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 ...

Linear Technology Corporation announces the LT8705, a very high efficiency (up to 98%) synchronous buck-boost DC/DC controller that operates from input voltages above, below or equal to the regulated ...

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 ...

The circuit is suitable for small power supplies, op-amp circuits, analogue electronics experiments, and various DIY projects ...
