ADP1864AUJZ-R7

Overview

The ADP1864AUJZ-R7 is a non-synchronous buck controller from Analog Devices, designed for step-down DC/DC conversion. It operates at a fixed switching frequency of 580 kHz and supports an output current capability of up to 5 A. The device regulates output voltages ranging from 800 mV to 14 V with a maximum duty cycle of 100%. It functions within an extended temperature range of -40°C to +125°C and is housed in a TSOT-6 surface-mount package.

Feature Summary

Implements constant frequency current-mode control architecture for stable regulation
Supports 100% maximum duty cycle operation for low dropout performance
Integrates shutdown functionality for power management efficiency

Applications

Powering multiple ADCs and operational amplifiers requiring negative voltage rails
General-purpose step-down DC/DC conversion in portable electronics
Industrial control systems requiring robust power management

Procurement Notes

Verify the specific suffix R7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with TSOT-6 footprint requirements during PCB layout. Cross-reference thermal dissipation needs with the 5 A output capability under expected load conditions. Confirm RoHS compliance status through the manufacturer's latest certification records before finalizing procurement orders.

Selection Notes

Select this component when a fixed-frequency non-synchronous buck topology is required for currents up to 5 A. The 580 kHz switching frequency offers a balance between size and efficiency. Consider the TSOT-6 package constraints for space-limited designs. Validate that the input voltage range aligns with the system supply before implementation.

Part Context

This part belongs to the ADP1864 series of switching controllers manufactured by Analog Devices Inc. It is categorized under PMIC - Power Management ICs, specifically within the Switching Controllers subcategory. The device is designed for applications requiring reliable step-down voltage regulation in compact form factors.
