Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9258B2FEER-G

The XC9258B2FEER-G is a synchronous step-down DC/DC converter designed for high efficiency and stable power supply applications. It features an output current capability of 1.0A and an adjustable output voltage range from 0.8V to 3.6V with an accuracy of ¬±2.0%. 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, allowing customization for specific applications. This regulator employs HiSAT-COT control for excellent transient response and includes automatic PWM/PFM switching control, which optimizes efficiency across varying load conditions. It incorporates several protection features, including thermal shutdown, current limit, and under-voltage lockout (UVLO). The XC9258B2FEER-G also supports a soft-start function with a typical time of 0.3ms and has a low standby current consumption of 1.0OºA or less. The product is available in SOT-25 and USP-6C packages and is compliant with EU RoHS standards, making it suitable for environmentally conscious designs. Applications include smartphones, Bluetooth devices, portable game consoles, digital cameras, and wearable technology.
