New buck DC/DC converter integrated circuits (ICs) with built-in metal oxide-semiconductor field-effect transistors (MOSFETs) from ROHM support high voltages and currents in factory automation equipment such as programmable logic controllers/inverters and 5G base stations that handle high power.
Recent years have seen evolving markets of battery-driven applications and advanced industrial equipment such as 5G base stations and factory automation systems equipped with new functions utilizing artificial intelligence and the internet of things. This demands power supply ICs that are not only compact and operate at high efficiency, but also deliver large currents for operating multiple functions and can withstand high voltages to prevent damage from sudden surges (due to lighting, for example).
The BD9G500EFJ-LA and BD9F500QUZ are non-isolated DC/DC converter ICs developed by utilizing proprietary analog design technology based on high voltage bipolar complementary metal-oxide-semiconductor power processes to provide the power supply functionality required by increasingly sophisticated industrial equipment.

In addition to a best-in-class 80 V withstand voltage for 48 V power supply systems, the BD9G500EFJ-LA with built-in MOSFET delivers the largest output current in its class (5 A), contributing to higher reliability and functionality in charging and 5G base stations that handle large power. At the same time, the BD9F500QUZ with built-in Nano Pulse Control technology achieving a high step-down ratio provides 39 V withstand voltage and 5 A output current in a compact, low-profile package (3.0 mm × 3.0 mm × 0.4 mm). Moreover, the product features an over current protection as SEL1/SEL2 pins can be selected. These features are ideal for 24 V power supply systems – enabling support for higher functionality and greater miniaturization in a wide range of advanced industrial equipment (factory automation, for example).
