Overview
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 specifically for low-voltage memory termination • Up to 7A VTT Current applications such as DDR3 and GDDR3/4/5.
The MIC5165 • Tracking programmable output offers a simple, low-cost JEDEC-compliant solution for • Power Good signal terminating high-speed, low-voltage digital buses with a • Wide bandwidth Power Good (PG) signal.
• Logic-controlled enable input The MIC5165 controls two external N-Channel MOSFETs to form two separate regulators.
It operates by switching • Requires minimal external components between either the high-side MOSFET or the low-side • DDR3, GDDR3/4/5 memory termination MOSFET, depending on whether the current is being • -40°C < TJ < +125°C 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 Applications programmed by forcing the reference voltage externally to • Desktop Computers the desired voltage.
• Servers The MIC5165 operates from an input voltage as low as • Notebook computers 0.
75V up to 6V, with a second bias supply input required for operation.
The MIC5165 is available in a tiny MSOP-10 • Workstations package with an operating junction temperature range of • DDR3 andGDDR3/4/5 Memory Termination –40°C to +125°C.
