Converters that employ synchronous rectification, such as DC/DC converters, are disclosed. These converters can control their synchronous rectifiers to selectively block or pass a negative current from flowing in their output lines. Also disclosed are converters which can operate as slaves based on timing signals from other daisy-chained converters. Open-loop synchronous rectifier driving circuitry is further disclosed to allow converters to operate independently of any timing information from their output stages.
