Synchronous buck regulators offer high efficiency and are popular in applications in which available input voltages are 12V or less. However, as input voltage approaches 100V, wide-range-regulator ...

This circuit provides ±12V regulated DC output based on LM7812 and LM7912 that are National Semiconductors’ two of the most popular positive and negative three terminal voltage regulators. The circuit ...

You can generate a tiny dc supply voltage of a just a few hundred millivolts using an additional positive voltage connected to the feedback resistor of a dc-dc converter. The need for such a ...
