Abstract
A buck converter having a synchronous rectifier topology that performs current sensing at the low-side switch and employs 'valley current control' to terminate a discharging phase and commence a charging phase of the converter. The buck converter is able to withstand high operating frequencies and low duty cycles to produce a low output voltage from a given high input voltage.
