6位可编程2-, 3-, 4相同步降压控制器 6-Bit Programmable 2-, 3-, 4-Phase Synchronous Buck Controller
GENERAL DESCRIPTION
The ADP3180 is a highly effi cient multiphase synchronous buck switching regulator controller optimized for converting a 12 V main supply into the core supply voltage required by high per formance Intel processors. It uses an internal 6-bit DAC to read a voltage identifi cation VID code directly from the processor, which is used to set the output voltage between 0.8375 V and 1.6 V, and uses a multimode PWM architecture to drive the logic level outputs at a programmable switching frequency that can be
optimized for VR size and efficiency.
FEATURES
Selectable 2-, 3-, or 4-Phase Operation at up to 1 MHz per Phase
14.5 mV Worst-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 0.8375 V to 1.6 V Output
Programmable Short Circuit Protection with Programmable Latch-Off Delay
APPLICATIONS
Desktop PC Power Supplies for:
Next Generation Intel® Processors
VRM Modules
