MIC5165

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 andGDDR...
