Description

SD VT2 CT CMPT OFF-TIME CONTROL ADP3157 DAC VID3 VID4 The ADP3157 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 ADP3157 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 ADP3157 uses a current mode, consta
