The XC9141D55DMR-G is a 0.8A Synchronous Step-up DC/DC Converter manufactured by Torex Semiconductor. This converter is designed for use in portable electronic devices and improves microprocessor system efficiency. It combines a step-up regulator controller with synchronous MOSFET power switches, an oscillator, and extensive fault protection capabilities to provide a reliable solution to multiple power management needs. It features short-circuit protection, over-current protection, over-temperature protection, and thermal shutdown protection to ensure safe operation of the converter. It also has a wide input voltage range from 2.4V to 30V and will provide a fixed output voltage of 5V with a peak efficiency of up to 95%. Additionally, it has an adjustable soft-start circuit and an active-high enable input, making it easy to control from an external digital signal. This part is ideal for consumer electronics, automotive, and home appliances where low power is needed with a compact form factor.
