G5616 - Complete DDR / DDRII and DDRIII Memory Solution Synchronous Buck PWM Controller

Download the G5616 datasheet PDF. This datasheet also covers the G5616-GlobalMixed variant, as both devices belong to the same complete ddr / ddrii and ddriii memory solution synchronous buck pwm controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The G5616 is intended for DDR/SSTL-2, DDRII/SSTL-18 and DDRIII memory systems.

It integrates a synchronous buck PWM controller with a 3-A sink-source linear regulator and buffered reference.

Key Features

  • Synchronous Buck Controller (VDDQ).
  • Ultra-High Efficiency.
  • No Current-Sense Resistor (Lossless ILIMIT).
  • Quasi-PWM with 100ns Load-Step Response.
  • 1.8V(DDRII) /1.5V(DDRIII) Fixed or Adjustable to 2.5V(DDR) or 0.75V to 3.6V Adjustable Output Range.
  • 2V to 24V Battery Input Range.
  • 400kHz Switching Frequency.
  • OVP & UVP of VDDQ Output.
  • Drives Large Synchronous-Rectifier FETs.
  • Power-Good Indicator.
  • 3-A LDO.
