G5316

Global Mixed-mode Technology

Complete DDR2, DDR3 and DDR3L Memory

Solution Synchronous Buck PWM Controller,

2A LDO, Buffered Reference

Features

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.

•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

The PWM controller uses constant on-time control

scheme to handle wide input/output voltage ratios with

ease and provides 100ns “instant-on” response to

load transients while maintaining a relatively constant

switching frequency. The G5316 achieves high effi-

ciency at a reduced cost by eliminating the cur-

rent-sense resistor found in traditional current-mode

PWMs. Efficiency is further enhanced by an ability to

drive very large synchronous rectifier MOSFETs. Sin-

gle-stage buck conversion allows these devices to

directly step down high-voltage batteries for the high-

est possible efficiency.

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 Ca-

pacitance

The 2A sink/source tracking termination regulator is

specifically designed for low-cost/ low-external com-

ponent count systems. The regulator contains a high

speed operational amplifier that provides fast load

transient response with only 10µF of ceramic output

capacitance. The G5316 supports remote sensing

functions and all features required to power the DDR2

/DDR3 /DDR3L VTT bus termination according to the

JEDEC specification. In addition, the G5316 includes

integrated sleep-state controls placing VTT in High-Z

in S3 (suspend to RAM) and soft-off for VTT and

VTTREF in S4/S5 (Shutdown).

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 Surg-

ing Current

Over Current Protection of VTT Output

Thermal Shutdown Protection

Applications

Notebook Computers

CPU Core Supply

Chipset/RAM Supply as Low as 0.7V

The G5316 provides OVP, UVP, over current and

thermal shutdown protection functions and is available

in a 20-pin 3X3 TQFN package.
