Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9258A30EMR-G

The XC9258A30EMR-G is a synchronous step-down DC/DC converter from the XC9258 series, 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%, allowing for fine-tuning in increments of 0.05V. 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. This regulator employs HiSAT-COT control for excellent transient response and includes automatic PWM/PFM switching control, which enhances efficiency across a wide load range. It incorporates several protection features, including thermal shutdown, current limit, and under-voltage lockout (UVLO), ensuring reliable operation. The XC9258A30EMR-G also supports a soft-start function with a typical time of 0.3ms and can be used with ceramic capacitors. 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.
