CPC H02M 3/33571 (2021.05) [H02M 1/0035 (2021.05); H02M 3/01 (2021.05)] | 20 Claims |
1. A circuit comprising:
a primary side including:
a first switch;
a second switch; and
a controller coupled to the first switch and to the second switch, wherein the controller is configured to:
increase an off-time for the first switch and the second switch in response to determining that a primary side current is below a first threshold;
decrease the off-time for the first switch and the second switch in response to determining that the primary side current is above a second threshold, wherein the second threshold is higher than the first threshold;
initiate a burst mode in response to determining that the primary side current falls below a third threshold, wherein the third threshold is higher than the second threshold; and
exit the burst mode in response to determining that the primary side current exceeds the third threshold; and
a secondary side coupled to the primary side.
