ADP3197 Datasheet (Analog Devices) - 6-Bit Programmable 2-/3-Phase Synchronous Buck Controller

ADP3197, 6-Bit Programmable 2-/3-Phase Synchronous Buck Controller

The ADP31971 is a highly efficient multiphase synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high performance, Advanced Micro Devices, AMD processors.

It uses an internal 6-bit digital-to-analog converter (DAC) to
