MIC5164

Dual Regulator Controller for DDR3

GDDR3/4/5 Memory and High-Speed

Bus Termination

General Description

Features

The MIC5164 is a dual regulator controller designed for

high speed bus termination. It offers a simple, low-cost

JEDEC-compliant solution for terminating high-speed, low-

voltage digital buses (i.e. DDR, DDR2, DDR3, SCSI, GTL,

SSTL, HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc)

with a Power Good (PG) signal.

• Input voltage range: 1.35V to 6V

• Up to 7A V_TTCurrent

• Tracking programmable output

• Power Good (PG) signal

• Wide bandwidth

• Logic controlled enable input

• Requires minimal external components

• DDR, DDR2, DDR3, memory termination

• −40°C < T_J< +125°C

• JEDEC-compliant bus termination for SCSI, GTL, SSTL,

HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc

The MIC5164 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 sunk by the regulator.

Designed to provide

a universal solution for bus

termination regardless of input voltage, output voltage, or

load current, the desired MIC5164 output voltage can be

programmed by forcing the reference voltage externally to

the desired voltage.

• Tiny MSOP-10 package

Applications

The MIC5164 operates from an input of 1.35V to 6V, with

a second bias supply input required for operation. It is

available in the tiny MSOP-10 package with an operating

junction temperature range of −40°C to +125°C.
