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.
