Lossless current sensing in buck converters working with low duty cycles and high clock frequencies |
摘要 |
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.
