MIC5162
Dual Regulator Controller for DDR3
GDDR3/4/5 Memory and High-Speed
Bus Termination
General Description
Features
The MIC5162 is a dual regulator controller designed for
high speed bus termination. It offers a simple, low-cost
JEDEC compliant solution for terminating high-speed, low-
voltage digital buses (i.e. DDR, DDR2, DDR3, SCSI, GTL,
SSTL, HSTL, LV-TTL, Rambus, LV-PECL, LV-ECL, etc).
The MIC5162 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 upon whether the current is being
sourced to the load or sunk by the regulator.
Designed to provide a universal solution for bus
termination regardless of input voltage, output voltage, or
load current. The desired MIC5162 output voltage can be
programmed by forcing the reference voltage externally to
desired voltage.
The MIC5162 operates from an input of 1.35V to 6V, with
a second bias supply input required for operation. It is
available in a tiny MSOP-10 package with operating
junction temperature range of -40°C to +125°C.

Pin Function
Bias Supply Input. Apply 3V-6V to this input for internal bias to the controller.
Enable (Input): CMOS compatible input. Logic high = enable, logic low = shutdown.
The enable pin can be tied directly to VDDQ or VCC for functionality. Do not float the
enable pin. Floating this pin causes the enable to be in an undetermined state.
Input Supply Voltage.
Reference voltage equal to half of VDDQ. For internal use only.
Ground.
Feedback input to the internal error amplifier.
Compensation (Output): Connect a capacitor and resistor from COMP pin to
feedback pin for compensation of the internal control loop.
Low-side drive: Connects to the Gate of the external low-side MOSFET.
High-side drive: Connects to the Gate of the external high-side MOSFET.
Not internally connected.
