DIODES Incorporated PMIC - PMIC - Voltage Regulators - DCDC Switching Regulators - AUR9721AGD AUR9721AGD

The AUR9721AGD is a high-efficiency step-down DC-DC voltage converter designed for various applications, including LCD TVs, set-top boxes, and portable devices. It operates within an input voltage range of 2.7V to 5.5V and can deliver an output current of up to 2A. The output voltage is adjustable from 0.8V to 0.9 times the input voltage, making it versatile for different power requirements. This device features a peak-current mode architecture with built-in synchronous power MOSFETs, which enhances efficiency and reduces the need for external components, such as Schottky diodes. The internal switching frequency is set at 1.5MHz, allowing for the use of smaller surface mount inductors and capacitors, which is beneficial for compact designs. Additional protective features include Soft Start (SS), Under Voltage Lock Out (UVLO), Thermal Shutdown Detection (TSD), and short circuit protection, ensuring reliable operation in various conditions. The AUR9721AGD is packaged in a DFN-3vó3-10 format and is suitable for automotive applications that require compliance with specific quality standards.
