GENERAL DESCRIPTION
The ADP3190/ADP3190A1 are highly efficient, multiphase,
synchronous buck switching regulator controllers optimized for
converting a 5 V or 12 V main supply into the core supply voltage
required by high performance Intel processors. They use an
internal 6-bit DAC to read a voltage identification (VID) code
directly from the processor, which is used to set the output
voltage between 0.8375 V and 1.6 V. The devices use a multimode
PWM architecture to drive the logic-level outputs at a
programmable switching frequency that can be optimized for
VR size and efficiency. The phase relationship of the output
signals can be programmed to provide 2-, 3-, or 4-phase
operation, allowing for the construction of up to four
complementary buck switching stages.
The ADP3190/ADP3190A also include programmable, no-load
offset and slope functions to adjust the output voltage as a function
of the load current, so it is always optimally positioned for a
system transient. The ADP3190/ADP3190A also provide
accurate and reliable short-circuit protection, adjustable current
limiting, and a delayed power good output that accommodates
on-the-fly output voltage changes requested by the CPU.

ADP3190
The ADP3190 is a replacement for the ADP3188. A built-in
shunt regulator allows the part to be connected to the 12 V
system supply through a series resistor.
The devices are specified over the commercial temperature
range of 0°C to +85°C and are available in a 28-lead TSSOP and
a 28-lead QSOP.

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
Absolute maximum ratings apply individually only, not in
combination. Unless otherwise specified, all other voltages
are referenced to GND.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.
