12-V / 100-A negative-to-positive synchronous buck-boost reference design for power amplifiers

Overview

TopologyBuck-Boost Converter
Input voltage-60 - -36 V
Output 114.5 V / 100 A
IC revision001

Description

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.

Features

  • 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

Typical applications

  • Active antenna system mMIMO (AAS)
