Product details

Description

R VT2 CT CMP ADP3155 DAC 1.20V The ADP3155 is a highly efficient synchronous buck switching regulator controller optimized for converting the 5 V main supply into the core supply voltage required by the Pentium III and other high performance processors.The ADP3155 uses an internal 5-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 1.3 V and 3.5 V.The ADP3155 uses a currentmode, constant off-time architecture
