AUR9717AGD

Overview

The AUR9717AGD is a dual-output synchronous buck switching voltage regulator manufactured by Diodes Incorporated. It operates with an input voltage range of 2.5V to 5.5V and provides two adjustable positive outputs, each capable of delivering up to 1A of current. The output voltage for both channels is adjustable from 1V to 3.3V. The device integrates a fixed switching frequency of 1.5MHz and functions within a junction temperature range of -40°C to 80°C. It is housed in a 10-WFDFN package with exposed pad.

Feature Summary

• Dual independent synchronous buck converter channels providing separate regulated outputs
• Adjustable output voltage range supporting various logic levels and power rails
• Integrated synchronous rectification for improved efficiency across load conditions

Applications

• Portable electronic devices requiring multiple low-voltage power domains
• Embedded systems needing compact dual-rail power management solutions
• Industrial control modules utilizing single-supply architectures

Procurement Notes

Verify component authenticity through authorized Diodes Incorporated distributors or certified partners. Confirm the specific ordering suffix matches design requirements. Review the latest datasheet for pinout compatibility and thermal performance specifications before integration into final assemblies.

Selection Notes

Select this component when dual isolated buck converters are required within a single supply rail. Ensure the 1A per channel current rating meets peak load demands. Consider the 1.5MHz switching frequency for passive component size optimization compared to lower-frequency alternatives.

Part Context

This part belongs to the AUR971x series of high-efficiency DC-DC converters designed for space-constrained applications.
