TPS40322 - Dual Output or Two-Phase Synchronous Buck Controller

Datasheet Summary

Description

The TPS40322 device is a dual-output, synchronous buck controller.

It can also be configured as a singleoutput, two-phase controller.

The 180° out-of-phase operation reduces the input current ripple and extends the input capacitor lifetime.

Features

  • 1 Dual-Output or Two-Phase Synchronous Buck Controller.
  • 180° Out-of-Phase Reduces Input Ripple.
  • Input Voltage Range: 3 V to 20 V.
  • Output Voltage Range: 0.6 V to 5.6 V.
  • Adjustable Frequency: 100 kHz to 1 MHz.
  • Bidirectional SYNC Pin With 0°/180° or 90°/270° Phase Shift.
  • Voltage Mode Control With Input Feedforward.
  • Accurate Current Sharing for Two-Phase Operation.
  • Individual Power Good Outputs.
  • Individual Enab.
