... Current-Mode Logic (CML) outputs provide similar performance to LVPECL but do not require an external bias and so CML is an option when an LVPECL type output is required but power consumption is a concern. CML outputs need to be ac-coupled since they cannot provide sufficient current to bias other d ...

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.
