General Description
The G5316 is intended for DDR2, DDR3 and DDR3L memory systems. It integrates a synchronous buck PWM controller with a 2-A sink-source linear regulator and buffered reference.

FEATUREs
● Synchronous Buck Controller (VDDQ)
   ◾ Ultra-High Efficiency at Light and Heavy Load
      with Auto-skip Function
   ◾ No Current-Sense Resistor (Lossless ILIMIT)
   ◾ Quasi-PWM with 100ns Load-Step Response
   ◾ 0.7V to 1.8V Adjustable Output Range
   ◾ 3V to 28V Battery Input Range
   ◾ 0.8% Vref Accuracy
   ◾ Supports Soft-off in S4/S5 States
   ◾ Selectable 300k/400kHz Switching Frequency
   ◾ OVP & UVP of VDDQ Output
   ◾ Drives Large Synchronous-Rectifier FETs
   ◾ Power-Good Indicator

● 2-A LDO (VTT), Buffered Reference (VTTREF)
   ◾ VLDOIN Voltage Range: 1.2 V to 3.6 V
   ◾ Requires Only 10µF Ceramic VTT Output Capacitance
   ◾ Supports High-Z in S3 and Soft-Off in S4/S5
   ◾ Integrated Divider Tracks 1/2 VDDQSNS for
      Both VTT and VTTREF
   ◾ Remote Sensing (VTTSNS)
   ◾ ±20mV VTT and 0.8% VTTREF Accuracy
   ◾ 10mA Buffered Reference (VTTREF)
   ◾ Built-In Soft-Start to Reduce the VLDOIN Surging Current
   ◾ Over Current Protection of VTT Output
   ◾ Thermal Shutdown Protection

APPLICATIONs
