Abstract
A circuit includes a timer circuit configured to generate a first control signal defining a first time period and a second control signal defining a second time period. A controller is configured to control a high-side and a low-side transistor of a half-bridge circuit in response to the first and second control signals only during a first switching cycle of the half-bridge circuit. The half-bridge circuit includes a bootstrap capacitor coupled to a node between the high-side and low-side transistors. The controller turns on the low-side transistor for the first time period during the first switching cycle and configured turns off the low-side and the high-side transistors for the second time period during the first switching cycle.
