ADP3161 Product details

GENERAL DESCRIPTION
The ADP3161 is a highly efficient dual output synchronous buck switching regulator controller optimized for converting a 5 V or 12 V main supply into the core supply voltage required by high-performance processors such as Pentium® III. The ADP3161 uses 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. The ADP3161 uses a current mode PWM architecture to drive two logic-level outputs at a programmable switching frequency that can be optimized for VRM size and efficiency. The output signals are 180 degrees out of phase, allowing for the construction of two complementary buck switching stages.
