Torex Semiconductor, Ltd. Voltage Regulators - DC DC Switching Regulators XC9140A4114R-G

The XC9140A4114R-G is a step-up synchronous DC/DC converter designed for high efficiency in portable applications. It operates with an input voltage range of 0.9V to 5.5V and can start up from as low as 0.9V, making it suitable for devices powered by single alkaline or nickel-metal hydride batteries. The converter features a low quiescent current of 6.3OºA, which is beneficial for battery-operated devices. This product includes an internal 0.6Oc N-channel driver transistor and a 0.65Oc P-channel synchronous rectifier switch transistor, enabling efficient power conversion. The output voltage can be set between 1.8V and 5.0V, with a maximum output current of 80mA at 3.3V. Additionally, a version with an Under Voltage Lock-out (UVLO) function is available, which helps reduce battery leakage by disabling the IC when the input voltage drops below a specified threshold. The XC9140A4114R-G is compatible with ceramic capacitors and operates over a temperature range of -40¬8C to 85¬8C. It is packaged in SOT-25 and USP-6EL formats and complies with EU RoHS standards, making it an environmentally friendly option for engineers looking for reliable voltage regulation solutions in compact designs.
