Sizing the UCC3913 Charge-Pump Capacitor
... LCA turns on the hot-swap FET. The amount of droop increases with the gate voltage slew rate and capacitance. If the droop is large enough to trip the charge-pump UVLO comparator, then the LCA shuts off, and it is not possible to turn on the FET. The UCC3919 data sheet recommends a 0.01-µF to 0.1-µF ...

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.
