Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9141A43D0R-G

The XC9141A43D0R-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 0.3Oc for both the N-channel driver and P-channel switching transistors. The device can start with an input voltage as low as 0.9V and is designed to generate a fixed output voltage of 4.3V, making it suitable for applications powered by single alkaline or nickel metal hydride batteries. The output voltage can be adjusted within a range of 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. Protection features include over-current limit and output short-circuit protection, ensuring reliable operation. The XC9141A43D0R-G is compliant with EU RoHS standards and operates within a temperature range of -40¬8C to 85¬8C. It is packaged in a compact SOT-25 format, making it suitable for space-constrained designs in portable and wearable devices.
