VID

DAC

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.

Figure 1.

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 uses a multimode architecture¹to 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

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.
