Torex Semiconductor, Ltd. PMIC - Voltage Regulators - DC DC Switching Regulators XD9260A2DDER-Q

The XD9260A2DDER-Q is a synchronous step-down DC/DC converter designed for high efficiency and stability in power supply applications. It operates with an input voltage range of 2.7V to 5.5V and can provide an output voltage from 0.8V to 3.6V with an accuracy of ¬±2.0%. The device supports an output current of up to 1.5A and features a choice of oscillation frequencies at 1.2MHz or 3.0MHz, allowing for flexibility in various applications. This regulator employs HiSAT-COT control technology, which enhances transient response and efficiency across a wide load range. It includes several protection features such as thermal shutdown, current limit, and under-voltage lockout (UVLO). The quiescent current is low at 25OºA, and during standby, it can reduce current consumption to 1.0OºA or less. The soft-start function enables quick turn-on, typically within 0.3ms. The XD9260A2DDER-Q is suitable for automotive applications, including car navigation systems and audio devices, and is compliant with AEC-Q100 Grade 2 standards. It is packaged in a compact USP-6C format, making it suitable for space-constrained designs.
