Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9141E54CMR-G

The XC9141E54CMR-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 N-channel driver transistor and a P-channel switching transistor, featuring an ON resistance of 0.3Oc. 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 a single alkaline or nickel-metal hydride battery. The output voltage is adjustable from 1.8V to 5.5V in 0.1V increments, and the device supports oscillation frequencies of either 1.2MHz or 3.0MHz, allowing for flexibility in design. The XC9141E54CMR-G includes several protective features such as over-current limit and output short-circuit protection, ensuring reliability in various applications. It is designed for use in portable equipment, wearable devices, and other battery-operated applications, with an operating temperature range of -40¬8C to 85¬8C. The product is compliant with EU RoHS standards and is available in compact SOT-25, USP-6C, and WLP-6-01 packages.
