Overview
The AUR9703AGH is a high-efficiency step-down DC-DC voltage converter manufactured by Diodes Incorporated. It features a synchronous Buck topology with an internal switching frequency of 1.5MHz, enabling the use of compact surface-mount inductors and capacitors. The device supports an input voltage range from 2.5V to 5.5V and delivers up to 800mA output current. Output voltage is adjustable between 600mV and 3.3V. It operates within a temperature range of -40°C to +85°C and is housed in a DFN-6 package.
Feature Summary
- Integrates synchronous power MOSFETs and internal compensators to minimize external component count.
- Utilizes constant frequency peak-current mode architecture for optimized efficiency across varying load conditions.
- Includes built-in soft start, under-voltage lockout, and thermal shutdown detection for reliable operation.
Applications
- Portable consumer electronics requiring space-constrained power solutions
- Battery-powered devices utilizing single-cell lithium-ion or lithium-polymer batteries
- Embedded systems needing efficient step-down regulation from 3V or 5V sources
Procurement Notes
Verify the specific suffix AGH against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Confirm RoHS compliance status directly with the supplier documentation. Ensure the procurement source provides valid traceability for electronic components intended for industrial or commercial deployment.
Selection Notes
Select this component when designing circuits that require a compact footprint due to the integrated synchronous design and 1.5MHz switching frequency. Consider the 800mA continuous current limit and the adjustable output voltage range when determining suitability for specific load requirements. Evaluate thermal performance within the specified operating temperature range.
