7-Bit, Programmable, 3-Phase, Mobile CPU Synchronous Buck Controller
The APD3212/NCP3218/NCP3218G is a highly efficient, multi−phase, synchronous buck switching
regulator controller. With

its integrated drivers, the APD3212/NCP3218/NCP3218G 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

CASE 485BA
ensure interleaved 2− or 3−phase operation. The APD3212/NCP3218/NCP3218G uses a multimode architecture
run at a programmable switching frequency and optimized for efficiency depending on the output current requirement. The APD3212/NCP3218/NCP3218G switches between single− and multi−phase operation to maximize efficiency with all load conditions.
