onsemi ADP4100
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.- Min Voltage : -300mV
- Max Voltage : 5.75V
- Max Operating Temp : 85°C
- Min Operating Temp : 0°C
