Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9141B30DMR-G

The XC9141B30DMR-G is a synchronous step-up DC/DC converter capable of delivering up to 0.8A output current. It operates efficiently with a built-in 0.3Oc N-channel driver and a 0.3Oc P-channel switching transistor. The device can start functioning with an input voltage as low as 0.9V to produce a stable output voltage of 3.3V under a 100Oc load, making it suitable for applications powered by single alkaline or nickel-metal hydride batteries. The output voltage is adjustable from 1.8V to 5.5V in 0.1V increments, and the device features selectable oscillation frequencies of either 1.2MHz or 3.0MHz. It includes various operational modes such as PWM and PWM/PFM control, depending on the specific type. Protection features include over-current limit and output short-circuit protection, ensuring reliability in various applications. This regulator is designed for portable devices, wearable technology, and other battery-operated equipment, operating within a temperature range of -40¬8C to 85¬8C. The XC9141B30DMR-G is compliant with EU RoHS standards and is available in compact packages such as SOT-25, USP-6C, and WLP-6-01.
