In recent years, we have witnessed the evolution of markets for battery-powered applications and advanced industrial equipment, such as 5G base stations and factory automation systems equipped with new features incorporating AI and IoT. This trend demands power integrated circuits that are not only compact and highly efficient, but also capable of delivering large currents to operate multiple functions and withstanding high voltages to prevent damage from sudden surges (e.g., due to lighting).
The BD9G500EFJ-LA and BD9F500QUZ are non-isolated DC/DC converter integrated circuits that have been developed using patented analog design technology based on high-voltage BiCDMOS power supply processes to provide the power supply functionality required by increasingly sophisticated industrial equipment.
In addition to a best-in-class 80V non-disruptive voltage for 48V power supplies, the BD9G500EFJ-LA with integrated MOSFET offers the highest output current in its class (5A), contributing to greater reliability and functionality in high-power 5G and charging base stations. Meanwhile, the BD9F500QUZ, with 
integrated Nano Pulse Control™ technology achieving a high buck ratio, provides a 39V non-disruptive voltage and 5A output current in a compact, low-profile package (3.0×3.0×0.4 mm). Furthermore, the product features overcurrent protection, as the SEL1/SEL2 pins are selectable. These characteristics are ideal for 24V power supplies, enabling greater functionality and miniaturization in a wide range of advanced industrial equipment (e.g., for factory automation).
