Torex Semiconductor, Ltd. PMIC - Voltage Regulators - DC DC Switching Regulators XC9258B20CER-G

The XC9258B20CER-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%. 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 automatic PWM/PFM switching control, which enhances efficiency across a wide load range, from light to heavy loads. It includes several protection features such as thermal shutdown, current limit, and under-voltage lockout (UVLO). The XC9258B20CER-G also incorporates a soft-start function with a typical turn-on time of 0.3ms and 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 devices.
