onsemi ADP3293
The ADP3293 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.FEATURES
● Selectable 2− or 3−Phase Operation at Up to 1 MHz per Phase● ±7 mV Worse−Case Differential Sensing Error
● Logic−Level PWM Outputs for Interface to External High Power Drivers
● Fast−Enhanced PWM FlexModet for Excellent Load Transient Performance
● TRDET to Improve Load Release
● Active Current Balancing Between All Output Phases
● Built−In Power−Good/Crowbar Blanking Supports Dynamic VID Code Changes
● Digitally Programmable 0.5 V to 1.6 V Output Supports VR11.1 Specification
● Programmable Overcurrent Protection with Programmable Latchoff Delay
● This is a Pb−Free Device Typical
