ADP3162JR

Special Purpose Regulators Overview

The ADP3162JR is a highly efficient dual-output synchronous buck switching regulator controller designed for converting 5V or 12V main supplies into core voltages for high-performance processors. It features an internal 5-bit DAC to read VID codes, setting output voltage between 1.05V and 1.825V with ±0.8% total accuracy over temperature. Operating in current-mode with PWM control, it supports up to 2000 kHz switching frequency within a 6.5V to 14V input range. The device utilizes ADOPT technology for superior load transient response and includes short circuit, overvoltage, and power good protection.

Special Purpose Regulators Feature Summary

• ADOPT Optimal Positioning Technology for superior load transient response
• Internal 5-bit DAC reads VID code directly from processor
• Active current balancing between both output phases
• Crowbar protection for microprocessors without additional external components

Special Purpose Regulators Applications

• Desktop PC power supplies
• Intel Tualatin processor core voltage regulation
• VRM modules
