ADP3162JR-REEL

Special Purpose Regulators Overview

The ADP3162JR-REEL is a highly efficient dual-output synchronous buck switching regulator controller manufactured by Analog Devices Inc. Designed for converting 5 V or 12 V main supplies into core voltages for high-performance processors, it features an internal 5-bit DAC that reads voltage identification codes directly from the processor to set output voltages between 1.05 V and 1.825 V. The device operates in current-mode with active current balancing between phases and complies with VRM 8.5 standards.

Special Purpose Regulators Feature Summary

• Adopts ADOPT technology for superior load transient response and minimized output capacitor count
• Integrates a 5-bit digitally programmable DAC for direct VID code reading
• Provides active current balancing between both output phases

Special Purpose Regulators Applications

• Desktop PC power supplies for Intel Tualatin processors
• VRM modules
• High-performance processor core supply conversion
