MIC5163 Datasheet | Micrel Semiconductor

Dual Regulator Controller for DDR3 GDDR3/4/5 Memory Termination General Description Features The MIC5163 is a dual regulator controller designed - 0.75V to 6V input supply voltage specifically for low voltage memory termination - Memory termination for: DDR3, GDDR3/4/5 applications such as DDR3 and GDDR3/4/5. The MIC5163 - Tracking programmable output offers a simple, low cost JEDEC pliant solution for - Logic controlled enable input terminating high-speed, low-voltage digital buses. - Wide bandwidth The MIC5163 controls two external N-Channel MOSFETs - Minimal external ponents required to form two separate regulators. It operates by switching between either the high-side MOSFET or the low-side - Tiny MSOP-10 package MOSFET, depending on whether the current is being - - 40°C < TJ < +125°C sourced to the load or being sinked by the regulator. Designed to provide a universal solution for memory Applications termination regardless of input voltage, output voltage, or load current; the desired MIC5163 output voltage can be - Desktop puters externally programmed by forcing the reference voltage. - Servers The MIC5163 operates from an input voltage as low as - Notebook puters 0.75V up to 6V, with a second bias supply input required - Workstations for operation. The MIC5163 is available in a tiny MSOP-10 package with an operating junction temperature range of - 40°C to +125°C.
