ADP3290

8-Bit, Programmable

2- to 4-Phase Synchronous

Buck Controller

The ADP3290 is a highly efficient, multi−phase, synchronous buck

switching regulator controller optimized for converting a 12 V main

supply voltage into the core supply voltage of high performance Intel

processors. It uses an internal 8−bit DAC to read a Voltage

Identification (VID) code directly from the processor, to set the output

voltage between 0.5 V and 1.6 V.

This device uses a multi−mode control architecture to drive the

logic−level PWM outputs. The switching frequency can be

programmed according to VR size and efficiency. The chip can

provide 2−, 3− or 4−phase operation, allowing for the construction of

up to four complementary buck switching stages.

The ADP3290 also includes programmable no load offset and load

line slope setting function that adjusts the output voltage as a function

of the load current, optimally positioning it for a system transient. The

ADP3290 also provides accurate and reliable short−circuit protection,

adjustable current limit, and a delayed power−good output that

accommodates On−The−Fly (OTF) output voltage changes requested

by the CPU.
