Bootstrap diode circuits

Abstract:

In described examples, bootstrap diode circuits include a first diode having a first diode input coupled to a voltage supply and a first diode output. Described bootstrap diode circuits additionally include a second diode having a second diode input coupled to the first diode output and a second diode output and a plurality of zener diodes coupled in series. The series-coupled zener diodes are further coupled in parallel with the second diode.
