ICS673-01 PLL Building Block Features Description
... The natural frequency, ωn, is approximately equal to the bandwidth (in radians/sec). As a general rule, the bandwidth should be at least 10 times less than the reference frequency, i.e., ωn ≈ 2π•BW ≤ REFIN/10. In this example, BW = REFIN/20, giving a bandwidth of 10 kHz. Using the first equation, C1 ...

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.
