ROHM’s New 80V Withstand 5A Output Power Supply ICs

Contributing to improved reliability and functionality in industrial equipment

Willich-Münchheide, Germany, June 30, 2021 – ROHM’s buck DC/DC converter ICs with built-in MOSFET – BD9G500EFJ-LA and BD9F500QUZ – support high voltages and currents in factory automation equipment such as PLCs/inverters, and 5G base stations that handle high power. (Fig. 1) 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 IoT. 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 (i.e. due to lighting). The BD9G500EFJ-LA and BD9F500QUZ are non-isolated DC/DC converter ICs developed by utilizing proprietary analog design technology based on high voltage BiCDMOS power processes to provide the power supply functionality required by increasingly sophisticated industrial equipment. In addition to a best-in-class 80V withstand voltage for 48V power supply systems, the BD9G500EFJ-LA with built-in MOSFET delivers the largest output current in its class (5A), contributing to higher reliability and functionality in charging and 5G base stations that handle large power. At the same time, the BD9F500QUZ Nano Pulse Control™ with fast transient response provides 39V withstand voltage and 5A output current in a compact, low-profile package (3.0×3.0×0.4mm). Moreover, the product features an over current protection as SEL1/SEL2 pins can be selected. These features are ideal for 24V power supply systems – enabling support for higher functionality and greater miniaturization in a wide range of advanced industrial equipment (i.e. factory automation). Also, the product is suitable for 12V to up to 48V battery driven applications.
