Abstract

In a circuit for DC-DC voltage converters, an amplifier has first and second inputs coupled to a reference voltage terminal and an output voltage terminal, respectively. A comparator has first and second inputs coupled to an amplifier output and a switching terminal, respectively. A logic circuit has inputs coupled to the comparator output and a clock terminal. A driver circuit has first and second inputs coupled to first and second logic outputs, respectively. A first transistor having a first control terminal coupled to the first driver output is coupled between a supply voltage terminal and the switching terminal. A second transistor is coupled between the switching terminal and a ground terminal, and has a second control terminal coupled to the second driver output. A threshold detection circuit is configured to provide a threshold signal responsive to a current through the second transistor crossing a current threshold.
