Santa Clara, CA and Kyoto, Japan, June 30, 2021 (GLOBE NEWSWIRE) -- ROHM  Semiconductor today announced two new buck DC/DC converter ICs with built-in MOSFET – the BD9G500EFJ-LA and BD9F500QUZ – ideal for applications supporting high voltages and currents in factory automation equipment (e.g., PLCs / 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 AI and IoT. This demands power supply ICs that are not only compact and operate at high efficiency, but that also deliver large currents for operating multiple functions that 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 high power. At the same time, the BD9F500QUZ with built-in Nano Pulse Control™ technology achieving a high step-down ratio provides 39V withstand voltage and 5A output current in a compact, low-profile package (3.0×3.0×0.4mm). Moreover, the product features overcurrent 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).
