NE57811S - Advanced DDR memory termination power with shutdown

Description

The NE57811 is designed to provide power for termination of a Double Data Rate (DDR) SDRAM memory bus.

It significantly reduces parts count, board space, and overall system cost compared to previous solutions.

Features

  • Fast transient response time.
  • Overtemperature protection.
  • Overcurrent protection.
  • Commercial (0 °C to +70 °C) temperature range.
  • Reduced need for external components (switching FETs, inductors, decoupling capacitors).

INTEGRATED CIRCUITS NE57811 Advanced DDR memory termination power with shutdown Product data Supersedes data of 2002 Jul 16 2003 Apr 02 Philips Semiconductors Philips Semiconductors Product data Advanced DDR memory termination power with shutdown NE57811 DESCRIPTION The NE57811 is designed to provide power for termination of a Double Data Rate (DDR) SDRAM memory bus. It significantly reduces parts count, board space, and overall system cost compared to previous solutions. The NE57811 DDR termination regulator maintains an output voltage (DDR reference bus voltage) that is one-half that of the RAM supply voltage. It is capable of providing up to ±3.5 A for sustained periods.
