ADP3212/NCP3218

FEATURES

GENERAL DESCRIPTION

The ADP3212/NCP3218 is a highly efficient, multiphase,

synchronous buck switching regulator controller. With its

integrated drivers, the ADP3212/NCP3218 is optimized for

converting the notebook battery voltage into the core supply

voltage required by high performance Intel processors. An internal

7-bit DAC is used to read a VID code directly from the processor

and to set the CPU core voltage to a value within the range of

0.3 V to 1.5 V. The ADP3212/NCP3218 is programmable for 1-,

2-, or 3-phase operation. The output signals ensure interleaved

2- or 3-phase operation.

Single-chip solution

Fully compatible with the Intel® IMVP-6.5™ specifications

Selectable 1- , 2-, or 3-phase operation with up to 1 MHz per

phase switching frequency

Phase 1 and Phase 2 Integrated MOSFET drivers

Input Voltage Range of 3.3 V to 22 V

Guaranteed ±± mV worst-case differentially sensed core

voltage error over temperature

Automatic power-saving mode maximizes efficiency with

light load during deeper sleep operation

Active current balancing between output phases

Independent current limit and load line setting inputs for

additional design flexibility

Built-in power-good blanking supports

voltage identification (VID) on-the-fly transients

7-bit, digitally programmable DAC with 0.3 V to 1.5 V output

Short-circuit protection with programmable latch-off delay

Clock enable output delays the CPU clock until the core

voltage is stable

Output power or current monitor options

4±-lead QFN 6x6mm (NCP321±)

4±-lead QFN 7x7mm (ADP3212)

The ADP3212/NCP3218 uses a multimode architecture run at a

programmable switching frequency and optimized for efficiency

depending on the output current requirement. The

ADP3212/NCP3218 switches between single- and multi-phase

operation to maximize efficiency with all load conditions. The chip

includes a programmable load line slope function to adjust the

output voltage as a function of the load current so that the core

voltage is always optimally positioned for a load transient. The

ADP3212/NCP3218 also provides accurate and reliable short-

circuit protection, adjustable current limiting, and a delayed

power-good output. The IC supports on-the-fly output voltage

changes requested by the CPU.

APPLICATIONS

Notebook power supplies for next-generation Intel processors

The ADP3212/NCP3218 are specified over the extended

commercial temperature range of -40°C to 100°C. The ADP3212

is available in a 48-lead QFN 7x7mm 0.5 mm pitch package.

The NCP3218 is available in a 48-lead QFN 6x6mm 0.4 mm

pitch package. Except for the packages, the ADP3212 and

NCP3218 are identical. ADP3212 and NCP3218 are Halogen-

Free, Pb-Free and RoHS compliant.
