AUR9707AGD

Overview

The AUR9707AGD is a high-efficiency step-down DC-DC voltage converter manufactured by Diodes Incorporated. It utilizes a constant frequency, peak-current mode architecture with built-in synchronous power MOSFETs and internal compensators to minimize external component requirements. The device features an internal switching frequency of 1.5MHz, enabling the use of small surface-mount inductors and capacitors. It supports an input voltage range from 2.5V to 5.5V and delivers up to 1A output current. The adjustable output voltage ranges from 600mV to 3.3V. Key protection features include Soft Start, Under Voltage Lock Out (UVLO), and Thermal Shutdown Detection.

Feature Summary

Integrates synchronous power MOSFETs and internal compensators for reduced external part count
Automatically switches between PWM and LDO modes to optimize efficiency across loading conditions
Includes built-in oscillator and timing capacitors for fixed 1.5MHz operation
Provides reliable application support through Soft Start, UVLO, and Thermal Shutdown

Applications

Portable electronic devices requiring compact power solutions
Battery-powered systems needing high-efficiency voltage regulation
Embedded applications utilizing space-saving surface mount designs

Procurement Notes

Verify component authenticity and datasheet revision status before integration. Confirm package compatibility and thermal performance for specific PCB layouts. Check end-of-life or obsolescence notices as availability may be limited. Ensure supply chain sources provide valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component for designs requiring a compact buck converter with integrated synchronous rectification. The 1.5MHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the adjustable output range and 1A current capability when matching load requirements. Evaluate thermal management needs based on the DFN12 package and operating temperature range.

Part Context

The AUR9707AGD belongs to the AUR97xx series of switching regulators from Diodes Incorporated. This series focuses on high-efficiency power conversion for portable and embedded applications. The device represents a solution for reducing bill-of-materials costs through internal integration of critical power stage and control elements.
