MIC5163
Dual Regulator Controller for DDR3
GDDR3/4/5 Memory Termination
General Description
The MIC5163 is a dual regulator controller designed
specifically for low voltage memory termination
applications such as DDR3 and GDDR3/4/5. The MIC5163
offers a simple, low cost JEDEC compliant solution for
terminating high-speed, low-voltage digital buses.
The MIC5163 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 being sinked by the regulator.
Designed to provide a universal solution for memory
termination regardless of input voltage, output voltage, or
load current; the desired MIC5163 output voltage can be
externally programmed by forcing the reference voltage.
The MIC5163 operates from an input voltage as low as
0.75V up to 6V, with a second bias supply input required
for operation. The MIC5163 is available in a tiny MSOP-10
