Product Summary

The SC2446A is a high-frequency dual synchronous stepdown switching power supply controller.  It provides outof-phase 

output gate signals.  The SC2446A operates in synchronous continuous-conduction mode. Both phases are capable of

 maintaining regulation with sourcing or sinking load currents, making the SC2446A suitable for generating both VDDQ

 and the tracking VTT  for DDR applications.
