ADP3212A, NCP3218A 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 http://onsemi.com 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 QFN48 to a value within the range of 0.3 V to 1.5 V. The APD3212A/ CASE 485AJ NCP3218A is programmable for 1-, 2-, or 3-phase operation. The output signals ensure interleaved 2- or 3-phase operation. 1 48 The APD3212A/NCP3218A uses a multimode architecture run at a programmable switching frequency and optimized for efficiency QFN48 depending on the output current requirement. The CASE 485AN APD3212A/NCP3218A switches between single- and multi-phase 1 48 operation to maximize efficiency with all load conditions. The chip includes a programmable load line slope function to adjust the output MARKING DIAGRAM voltage as a function of the load current so that the core voltage is 1 always optimally positioned for a load transient. The APD3212A/NCP3218A also provides accurate and reliable xxP321xA short-circuit protection, adjustable current limiting, and a delayed AWLYYWWG 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 xxx= Specific Device Code commercial temperature range of -40
