The RPX-4.0-R is a DC/DC buck converter power module with an integrated shielded inductor, designed for high power density applications. It operates over a wide input voltage range from 3.8V to 36VDC and delivers an output current of up to 4A. The output voltage is programmable from 1V to 7VDC using external resistors. Housed in a compact 5.0 x 5.5 x 4.1mm QFN package, the module includes features such as an enable pin, a power good signal, and built-in protections against short-circuits, overcurrent, and over-temperature faults. Its high power density and comprehensive protection features make it ideal for industrial automation, test and measurement, portable devices, and other high-density or weight-sensitive applications.
