The TLVR topology enables faster transient response and utilizes a dual winding power bead inductor.

Key Points: 
  • The TLVR topology enables faster transient response and utilizes a dual winding power bead inductor.
  • Traditionally, these applications have used single winding inductor used in a multi-phase buck topology which allows currents to be distributed though parallel paths or phases.
  • For the inductor, this space constraint creates skinny but tall components that can become mechanically unstable which limits the ability to shrink the inductor width.
  • The trans-inductor is very similar to a traditional one turn VR inductor, but has the addition of a second tightly coupled winding.
