NCP3218G

ADP3212, NCP3218, NCP3218G 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 http://onsemi.com 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 1 48 1 48 of 0.3 V to 1.5 V. The APD3212/NCP3218/NCP3218G is QFN48 QFN48 programmable for 1−, 2−, or 3−phase operation. The output signals CASE 485AJ 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.
