Beschreibung

This reference design is a negative- to-positive synchronous buck-boost converter for power amplifier applications. The circuit is powered from the nominal -48 V system source to provide an output voltage of +48 V at 25 A. The design uses two dual synchronous boost controllers for 4-phase operation at a switching frequency of 150 kHz. Output voltage adjustment to +30 V is jumper selectable. 1 through 4 phase operation is also jumper selectable.

Eigenschaften

  • Non-isolated inverting solution for higher power
  • Excellent phase current sharing for balanced thermal performance
  • Jumper selectable phase control
  • Compact design for minimum solution size
  • Jumper selectable output voltage control

Typische Anwendungen

  • Active antenna system mMIMO (AAS)
