ADP3158JR Product details

GENERAL DESCRIPTION

The ADP3158 and ADP3178 are highly efficient synchronous buck switching regulator controllers optimized for converting a 5 V main supply into the core supply voltage required by high performance processors. These devices use an internal 4-bit DAC to read a voltage identification (VID) code directly from the processor, which is used to set the output voltage between 1.3 V and 2.05 V. They use a current mode, constant off-time architecture to drive two N-channel MOSFETs at a programmable switching frequency that can be optimized for regulator size and efficiency.



FEATURES

  Optimally Compensated Active Voltage Positioning with Gain and Offset Adjustment (ADOPT™) for Superior Load Transient Response

  Complies with VRM Specifications with Lowest System Cost

  4-Bit Digitally Programmable 1.3 V to 2.05 V Output

  N-Channel Synchronous Buck Driver

  Total Accuracy ±0.8% Over Temperature

  Two On-Board Linear Regulator Controllers Designed to Meet System Power Sequencing Requirements

  High Efficiency Current-Mode Operation

  Short Circuit Protection for Switching Regulator

  Overvoltage Protection Crowbar Protects Microprocessors with No Additional External Components



APPLICATIONS

  Core Supply Voltage Generation for:

  Intel Pentium® III

  Intel Celeron™
