General Description

The MIC5163 is a dual regulator controller designed

specifically

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

package with an operating junction temperature range of

–40°C to +125°C.
