Torex Semiconductor, Ltd. PMIC - Voltage Regulators - DC DC Switching Regulators XC9257A28EMR-G

The XC9257A28EMR-G is a synchronous step-down DC/DC converter 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 2.8V with an accuracy of ¬±2.0%, and it can deliver an output current of up to 1.0A. The device operates within an input voltage range of 2.5V to 5.5V and offers selectable oscillation frequencies of 1.2MHz or 6.0MHz to suit various applications. The XC9257A28EMR-G employs HiSAT-COT control for excellent transient response and includes features such as thermal shutdown, under-voltage lockout (UVLO), and a soft-start function with a typical time of 0.3ms. In standby mode, it consumes less than 1.0OºA of current. The product is available in SOT-25 and USP-6C packages and is compliant with EU RoHS standards. It is suitable for applications in smartphones, Bluetooth devices, portable game consoles, digital cameras, and wearable technology.
