TPL51200 Series

3-A Sink and Source DDR Termination Regulator

Features

Description

◼

V_INVoltage: Support 2.5-V, 3.3-V and 5-V Power Rails

With the development of main processors in PCs and servers,

more and more source double-data-rate (DDR) memories are

required in the mainboard, where the input voltage becomes

lower and lower, and space limitation becomes higher and

higher.

V_LDOINVoltage Range: 1.1 V to 3.5 V

Flexible Input Voltage Tracking Directly from REFIN or

Through External Resistor Divider

3-A Sink and Source Current Capability for DDR

Termination

◼

Integrated Power MOSFETs

The TPL51200 series devices are 3-A sink and source DDR

termination regulators specifically designed for the DDR

applications with heavy space limitation. The TPL51200 series

devices implement a fast load-transient response and only

requires a minimum output capacitance of 20 μF.

Output Remote Sensing

Fast Load-Transient Response

Open-Drain Power Good to Monitor OUT Regulation

Built in Soft-Start and UVLO, Current Limit and Thermal

Shutdown Protection

◼

Support DDR, DDR2, DDR3, DDR3L, Low Power DDR3

and DDR4 VTT Applications

The TPL51200 series devices support a remote-sensing

function and all power requirements for DDR VTT bus

termination. In addition, the TPL51200 series devices provide

an open-drain PG signal for VTT regulation indication and an

EN signal that can be used to discharge VTT for DDR

applications.

◼

Operating Temperature Range: –40°C to +125°C

Small Package with 3×3 DFN-10

Pb−Free and are RoHS Compliant

Applications

The TPL51200 series devices are available in the thermally

efficient 10-pin 3×3 DFN package with thermal pad, and support

the operating temperature range from –40°C to +125°C.

◼

Memory VTT Regulator for DDR, DDR2, DDR3, DDR3L,

Low Power DDR3 and DDR4
