ADP4100 Overview
ADP4100 Product Preview Programmable Multi-Phase Synchronous Buck Converter The ADP4100 is optimized for converting a 12 V main supply into the core supply voltage required by high performance Intel processors. It uses an internal 8−bit DAC to read the voltage identification (VID) code directly from the processor, which is used to set the output voltage between 0.375 V and 1.6 V. Typical Applications • Servers • Desktop PC’s • POLs (Memory) http://onsemi.
