MIC5165 Datasheet | Micrel Semiconductor

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-pliant 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 ponents 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 puters the desired voltage. - Servers The MIC5165 operates from an input voltage as low as - Notebook puters 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 and GDDR3/4/5 Memory Termination - 40°C to +125°C.
