Abstract
In an embodiment, an SMPS comprises a half-bridge, and a driver configured to drive the half-bridge based on a PWM signal. The SMPS further comprising a first circuit coupled between the output of the driver and a control terminal of a high-side transistor of the half-bridge, wherein the first circuit is configured to maintain the first transistor on when the PWM signal has a duty cycle that is substantially 100%.
