MIC5165

Dual Regulator Controller for DDR3

GDDR3/4/5 Memory Termination

General Description

Features

The MIC5165 is a dual regulator controller designed

• Input voltage range: 0.75V to 6V

• Up to 7A V_TTCurrent

• Tracking programmable output

• Power Good signal

specifically

for

low-voltage

memory

termination

applications such as DDR3 and GDDR3/4/5. The MIC5165

offers a simple, low-cost JEDEC-compliant solution for

terminating high-speed, low-voltage digital buses with a

Power Good (PG) signal.

• Wide bandwidth

• Logic-controlled enable input

• Requires minimal external components

• DDR3, GDDR3/4/5 memory termination

• -40°C < T_J< +125°C

The MIC5165 controls two external N-Channel MOSFETs

to form two separate regulators. It operates by switching

between either the high-side MOSFET or the low-side

MOSFET, depending on whether the current is being

sourced to the load or being sunk by the regulator.

• Tiny MSOP-10 package

Designed to provide a universal solution for memory

termination regardless of input voltage, output voltage, or

load current, the desired MIC5165 output voltage can be

programmed by forcing the reference voltage externally to

the desired voltage.

Applications

• Desktop Computers

• Servers

• Notebook computers

• Workstations

The MIC5165 operates from an input voltage as low as

0.75V up to 6V, with a second bias supply input required

for operation. The MIC5165 is available in a tiny MSOP-10

package with an operating junction temperature range of

–40°C to +125°C.

• DDR3 andGDDR3/4/5 Memory Termination
