Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9141A22CMR-G

The XC9141A22CMR-G is a synchronous step-up DC/DC converter capable of delivering up to 0.8A output current. It operates efficiently with a low ON resistance of 0.3Ω for both the N-channel driver and P-channel switching transistors. This regulator can start functioning with an input voltage as low as 0.9V, 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, allowing flexibility for various applications. The device features a selectable oscillation frequency of either 1.2MHz or 3.0MHz, which can be tailored to specific requirements. Protection features include over-current limit and output short-circuit protection, enhancing reliability in portable and battery-operated devices. The XC9141A22CMR-G is compliant with EU RoHS standards and operates within a temperature range of -40°C to 85°C, making it suitable for a wide range of environments.
