TPS51916 - Synchronous Buck Controller

Description

The TPS51916 device provides a complete power supply for DDR2, DDR3, DDR3L, and DDR4 memory systems in the lowest total cost and minimum space.

It integrates a synchronous buck regulator controller (VDDQ) with a 2-A sink and 2-A source tracking LDO (VTT) and buffered low noise reference (VTTREF).

Features

  • 1 Synchronous Buck Controller (VDDQ).
  • Conversion Voltage Range: 3 V to 28 V.
  • Output Voltage Range: 0.7 V to 1.8 V.
  • 0.8% VREF Accuracy.
  • Selectable Control Architecture.
  • D-CAP™ Mode for Fast Transient Response.
  • D-CAP2™ Mode for Ceramic Output Capacitors.
  • Selectable 300 kHz, 400 kHz, 500 kHz, or 670 kHz Switching Frequencies.
  • Optimized Efficiency at Light and Heavy Loads with Auto-skip Function.
  • Supports Soft-.
