Abstract
Described embodiments include a boost circuit for a DC-DC voltage converter includes a first transistor coupled between an input voltage terminal and a boost terminal. A second transistor is coupled between the first control terminal and a switch terminal, and has a second control terminal coupled to the switch terminal. A capacitor is coupled between the boost terminal and the switch terminal. A third transistor has a third control terminal and first and second current terminals. The first current terminal is coupled to the first control terminal, and the third control terminal is coupled to an internal voltage supply terminal. A fourth transistor is coupled between the internal voltage supply terminal and the second current terminal, and has a fourth control terminal coupled to a drive terminal.
