AUR9705AUGD

Overview

The AUR9705AUGD 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 MOSFET switchers 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 suitable for portable applications. It automatically switches between normal PWM mode and LDO mode to optimize system power efficiency across varying load conditions. The unit provides reliable operation through integrated Soft Start (SS), Under Voltage Lock Out (UVLO), and Thermal Shutdown Detection (TSD) functions.
