Abstract: In some examples, a circuit includes a capacitor having a first terminal and a second terminal, the first terminal coupled to a voltage supply terminal of the circuit. The circuit also includes a transistor having a transistor gate, a transistor drain, and a transistor source, the transistor source coupled to ground and the transistor drain coupled to an input terminal of the circuit. The transistor is configured to conduct responsive to a gate signal received at the transistor gate, the gate signal based on a signal provided at the second terminal of the capacitor. The circuit also includes a Schmitt trigger having a Schmitt trigger input coupled to the transistor drain.

Abstract: A circuit includes a first driver, a second driver, and a burst mode control circuit coupled to the first and second drivers. The burst mode control circuit is configured to implement a burst mode operation having a burst soft-on portion and a burst portion. During the soft-on portion of the burst mode operation, the burst mode control circuit is configured to cause the first and second drivers to produce a first set of pulses of increasing pulse width. During the burst portion of the burst mode operation, the burst mode control circuit is configured to cause the first and second drivers to produce a second set of pulses of a constant pulse width.
