Designing an ultra low quiescent current buck switching regulator
The new buck regulator proposed in this thesis was designed to operate with only a few micro-amps of supply current during no load output conditions, while maintaining low output voltage ripple. The regulator also has high efficiency for current loads above an amp to make the converter useful in a …
