Product Description

GENERAL DESCRIPTION
The ADP3188 is a highlyefficient, multiphase, synchronous buck switching regulator controller optimized for converting a 12V main supply into the core supply voltage required by high
performance Intel processors. The part uses aninternal 6-bit DAC toread a voltage identification(VID) code directly from the processor, which is used to set the output voltage between 0.8375 V and 1.6 V.Ituses a multimode PWM architecture to drive the logic-level outputs ata programmable switching frequency that can be optimized for VR size and efficiency.
The phase relation ship of the output signals can be programmed to provide 2-, 3-, or4-phase operation, allowing the construction of up to four complementary buck switching stages.
FEATURES
Selectable 2-,3-or 4-phase operation at up to 1 MHz per phase
±9.5 mVworst-case differential sensing error over temperature
Logic-level PWM outputs for interface to external high power drivers
Active current balancing between all output phases
Built-in power good/crowbar blanking supports on-the-fly VID code changes
6-bit digitally programmable 0.8375V to 1.6 V output
Programmable short-circuit protection with programmablelatch-off delay
APPLICATIONS
Desktop PC power supplies for Next-generation Intel® processors VRM modules
