Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9141B27DER-G

The XC9141B27DER-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. The device 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 selectable oscillation frequencies of 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 XC9141B27DER-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.
