General Description

The ADP3158 and ADP3178 are highly efficient synchronous buck switching regulator controllers optimized for converting a 5 V main supply into the core supply voltage required by highperformance processors.

These devices use an internal 4-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 2.05 V.

They use a current mode, constant off-time architecture to drive two N-channel MOSFETs at a programmable switching frequency that can be optimized for regulator size and efficiency.
