GENERAL DESCRIPTION
The ADP3210 is a high efficiency, multiphase, synchronous,
buck-switching regulator controller optimized for converting
notebook battery voltage into the core supply voltage of high
performance Intel processors. The part uses an internal 7-bit
DAC to read voltage identification (VID) code directly from the
processor that sets the output voltage. The phase relationship of
the output signals can be configured for 1-, 2-, or 3-phase
operation, with interleaved switching.
The ADP3210 uses a multimode architecture1 to drive the logic-
level PWM outputs at a switching frequency selected by the
user depending on the output current requirement. The part
switches between multiphase and single-phase operation according
to a system signal provided by the CPU. Shedding phases as
function of the load maximizes power conversion efficiency under
different load conditions. In addition, the ADP3210 supports
programmable loadline resistance adjustment. As a result, the
output voltage is always optimally positioned for a load transient.

The chip also provides accurate and reliable short-circuit
protection with adjustable current limit threshold and a delayed
power-good output that is masked during on-the-fly output
voltage changes to eliminate false alarm.
The ADP3210 performance is specified over the extended
commercial temperature range of -10°C to 100°C. The chip is
available in a 40-lead QFN package.
