Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9142A42CMR-G

The XC9142A42CMR-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 4.2V, 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. It includes protection features such as over-current limit and output short-circuit protection, ensuring reliable operation. The XC9142A42CMR-G is compliant with EU RoHS standards and operates over a temperature range of -40¬8C to 85¬8C, making it suitable for a wide range of portable and wearable devices.
