TPS40140 - Stackable Controller

General Description

The TPS40140 is a multifunctional synchronous buck controller that can be configured to provide either a single-output 2-phase power supply or a power supply that supports two independent outputs.

Several TPS40140 controllers can be stacked up to a 16-phase single output power supply.

Key Features

  • 1 VDD from 4.5 to 15 V, With Internal 5-V Regulator.
  • VOUT from 0.7 V to 5.8 V.
  • Converts from 15-V Input to 0.7-V Output at 1 MHz.
  • Dual-Output or 2-Phase Interleaved Operation, Stackable to 16 Phases.
  • Supports Prebiased Outputs Programmable Switching Frequency up to 1 MHz/Phase.
  • 0.5% Internally Trimmed 0.7-V Reference.
  • 10-μA Shutdown Current.
  • Current Mode Control With Forced Current Sharing (1).
  • 1- to 40-V Power Stag.
