ADP3208C 7-Bit, Programmable,Dual-Phase, Mobile, CPU, Synchronous Buck Controller

PublishTime：2022-01-25

he ADP3208C is a highly efficient, multiphase, synchronous buck switching regulator controller. With its integrated drivers, the ADP3208C 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 phase relationship of the output signal sensures interleaved 2−phase operation.
The ADP3208C uses a multi−mode architecture run at a programmable switching frequency and optimized for efficiency depending on the output current requirement. The ADP3208C switches between single− and dual−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 ADP3208C also provides accurate and reliable short−circuit protection, adjustable current limiting, and a delayed power−good output. The IC supports On−The−Fly (OTF) outputvoltage changes requested by the CPU.
The ADP3208C is specified over the extended commercial temperature range of −10°C to 100°C and is available in a 48−leadLFCSP.
