ADP4100
Product Preview Programmable Multi-Phase Synchronous Buck Converter
The ADP4100 is an integrated power control IC for VR11.1 applications. The ADP4100 can be programmed for 1−, 2−, 3−, 4−, 5− or 6−phase operation, allowing for the construction of up to six complementary buck switching stages. The ADP4100 supports PSI, which is a power state indicator and can be used to reduce number of operating phases at light loads.
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.
Features
• Supports Both VR11 and VR11.
