    SRM4010 40A Synchronous Rectifier Module C OL OR AD O DIVISIO N DESCRIPTION The SRM4010 Module is a complete solution for implementing very high efficiency Synchronous Rectification and eliminates many of the problems with selfdriven approaches. The module connects to the transformer secondary of a Forward Converter to provide complete high current rectification at output voltages ranging from 5 volts down to 1.0 volt, in a thermally efficient surface mount package. Rectification Efficiency as high as 95% is achieved by avoiding cross conduction. Dedicated Ics provide effective Gate drive of the ultra low Rds(on) MOSFETs used in the module. In conventional self-driven approaches, the MOSFET drive ends as soon as the power transformer finishes resetting.
