TPS546D24A 2-Phase SWIFT™ Step-Down Converter

Overview

TopologyBuck Converter
Input voltage5-16 V
Output 10.8 V / 80 A

Description

The TPS546D24AEVM-2PH evaluation module (EVM) is a two-phase buck converter with two TPS546D24Adevices. The TPS546D24A device is a stackable synchronous buck with PMBus interface that can operate from a nominal 2.95-V to 16-V supply. The device allows programming and monitoring via the interface.Two TPS546D24A devices are configured as two-phase buck converter in factory default, output current is evenly distributed in the two devices; both the negative and positive output terminals are connected together.

Features

  • Regulated 0.8-V output up to 80-ADC steady-state output current
  • The output voltage is marginable and trimmable using the PMBus interface
  • Programmable UVLO, soft-start, and enable via the PMBus interface
  • Programmable overcurrent warning and fault limits and programmable response to faults via the PMBus interface
  • Programmable overvoltage and undervoltage warning and fault limits and programmable response to faults via the PMBus interface
  • Programmable turn-on and turn-off delays
  • Convenient test points for probing critical waveforms

Typical applications

  • Wireless infrastructure, Switcher, Router network, Server
  • Smart power systems, High-density power solutions
