CIRCUIT FUNCTION AND BENEFITS
... CIRCUIT DESCRIPTION This is a precise, fast sample-and-hold circuit. During the sample mode, SW2 is closed, and the output, VOUT, follows the input signal, VIN. In the hold mode, SW2 is opened, and the signal is held by the hold capacitor, CH. Due to switch and capacitor leakage current, the voltage ...

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.
