... Positive feedback occurs when some of the output feeds the input in a way that boosts the input value. Negative feedback exists when some of the output returns to the input, but it acts contrary to the input, in that it is of opposite polarity, and so diminishes the value of the input. When this inp ...

This drops some voltage across Rx, forcing current to flow into T1 and T2, starting up the circuit. – After the circuit is at the desired ...

Buck converter



A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12V in a desktop, 12-24V in a laptop) down to the 0.8-1.8V needed by the processor.
