Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9141A38CMR-G

The XC9141A38CMR-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 0.3Ω N-channel driver and a 0.3Ω 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 100Ω 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 features selectable oscillation frequencies of 1.2MHz or 3.0MHz to accommodate various application requirements. It includes several protective features such as over-current limit and output short-circuit protection, ensuring reliable operation. The XC9141A38CMR-G is designed for use in portable devices, wearable technology, and other applications requiring efficient power management. It operates within a temperature range of -40°C to 85°C and is compliant with EU RoHS standards.
