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 +12 V at 100 A. The design uses two dual synchronous boost controllers for 4-phase operation at a switching frequency of 100 kHz. Output voltage adjustment to +14.5 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
• Mounting option for bottom-side heat sink
• Jumper selectable output voltage control

Typische Anwendungen

• Active antenna system mMIMO (AAS)
