METHOD AND APPARATUS FOR CONTINUOUS CONDUCTION MODE OPERATION OF A MULTI-OUTPUT POWER CONVERTER

Abstract:

Methods and apparatus for continuous conduction mode operation in multi-output power converters are described herein. During a switching cycle, secondary current may be delivered via a diode to a secondary output. Prior to beginning a subsequent switching cycle, a diverting current may be provided to a lower voltage secondary output on a parallel path. In this way diode current may be reduced to substantially zero prior to the subsequent switching cycle.
