Torex Semiconductor, Ltd. PMIC - Voltage Regulators - DC DC Switching Regulators XC9261A29DER-G

The XC9261A29DER-G is a synchronous step-down DC/DC converter from the XC9261 series, designed for high efficiency and stable power supply applications. It features a built-in P-channel MOS driver and N-channel MOS switching transistor, allowing for the use of ceramic capacitors. The output voltage is internally set at 2.9V with an accuracy of ¬±2.0%, and it can deliver an output current of up to 1.5A. The device operates within an input voltage range of 2.7V to 5.5V and offers two selectable oscillation frequencies of 1.2MHz or 3.0MHz. This regulator employs HiSAT-COT control, which provides excellent transient response and efficiency across varying load conditions. In standby mode, it consumes less than 1.0OºA, making it suitable for low-power applications. Additional features include a soft-start function, under-voltage lockout (UVLO), and thermal shutdown protection. The XC9261A29DER-G is available in SOT-89-5 and USP-6C packages and is compliant with EU RoHS standards. It is suitable for applications in communication equipment, mobile devices, and power supplies for MCUs and FPGAs.
