TPS53681 - Step-Down Multiphase Controller

Datasheet Summary

Description

The TPS53681 is a multiphase step-down controller with dual channels, built-in non-volatile memory (NVM), and PMBus™ interface, and is fully compatible with TI NexFET ™power stage.

Features

  • 1 Conversion Input Voltage Range: 4.5 V to 17 V.
  • 8-Bit DAC with Selectable 5 mV or 10 mV Resolution and Output Ranges from 0.25 V to 1.52 V or 0.5 to 2.8125 V for Dual Channels.
  • Phase Configurations.
  • Maximum (6-Phase + 2-Phase) or (5-Phase + 3-Phase).
  • Minimum (1-Phase + 1-Phase).
  • Driverless Configuration for Efficient HighFrequency Switching.
  • Dynamic Output Voltage Transitions with Programmable Slew Rates via PMBus Interface.
