7-Bit, Programmable,

3-Phase, Mobile CPU

Synchronous Buck Controller

The APD3212A/NCP3218A is a highly efficient, multi−phase,

synchronous buck switching regulator controller. With its integrated

drivers, the APD3212A/NCP3218A 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 APD3212A/

NCP3218A is programmable for 1−, 2−, or 3−phase operation. The

output signals ensure interleaved 2− or 3−phase operation.

The APD3212A/NCP3218A uses a multimode architecture run at a

programmable switching frequency and optimized for efficiency

depending on the output current requirement. The

APD3212A/NCP3218A 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

APD3212A/NCP3218A also provides accurate and reliable

short−circuit protection, adjustable current limiting, and a delayed

power−good output. The IC supports On−The−Fly (OTF) output

voltage changes requested by the CPU.

The APD3212A/NCP3218A are specified over the extended

commercial temperature range of −40°C to 100°C. The ADP3212A is

available in a 48−lead QFN 7x7mm 0.5mm pitch package. The

NCP3218A is available in a 48−lead QFN 6x6mm 0.4mm pitch

package. Except for the packages, the APD3212A/NCP3218A are

identical. APD3212A/NCP3218A are Halogen−Free, Pb−Free and

RoHS compliant.
