Description

This two-phase synchronous buck operates from 24VDC and supplies an output of 15V@20A. Operation at 300KHz (per phase) delivers small size and greater than 96% efficiency.

Features
  • Efficiency approaches 97% at 12A load
  • Board length is approximately 94 mm
  • Reduced component size due to two phase operation
  • Test report available
