ADP3180JRU-REEL7

DC DC Switching Controllers Overview

The ADP3180JRU-REEL7 is a highly efficient multiphase synchronous buck switching regulator controller manufactured by Analog Devices Inc. Designed for converting a 12 V main supply into core supply voltages for high-performance Intel processors, it features an internal 6-bit DAC for direct VID code reading. The device supports selectable 2-, 3-, or 4-phase operation with a programmable switching frequency up to 1 MHz per phase. It utilizes a multimode PWM architecture and includes active current balancing between output phases. Key electrical parameters include a logic-level PWM interface for external drivers and a digitally programmable output voltage range of 0.8375 V to 1.6 V.

DC DC Switching Controllers Feature Summary

• Supports selectable 2-, 3-, or 4-phase synchronous buck operation with active current balancing across all output phases.
• Features a multimode PWM architecture allowing programmable switching frequencies optimized for size and efficiency.
• Includes built-in power good/crowbar blanking and supports on-the-fly VID code changes.

DC DC Switching Controllers Applications

• Desktop PC power supplies for next-generation Intel processors
• VRM (Voltage Regulator Module) designs

DC DC Switching Controllers Procurement Notes

Verify the specific suffix JRU against the official datasheet to confirm package type and temperature grade. Confirm RoHS compliance status as indicated in the manufacturer's documentation. Ensure the REEL7 packaging format matches production requirements. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and current availability status.

DC DC Switching Controllers Selection Notes

Select this component when designing power stages for Intel processors requiring direct VID interface. It is suitable for applications needing flexible phase counts (2 to 4) and high efficiency at 12 V input. Consider the internal 6-bit DAC resolution for voltage accuracy requirements. Evaluate the thermal performance based on the selected phase count and load conditions.

DC DC Switching Controllers Part Context
