80V Withstand 5A output power supply ICs

ROHM’s new buck DC/DC converter ICs with built-in MOSFET, support high voltages and currents in factory automation equipment such as PLCs/inverters, and 5G base stations that handle high power.

The BD9G500EFJ-LA and BD9F500QUZ address the growing demand for power supply ICs that are not only compact and operate at high efficiency, but also deliver large currents for operating multiple functions and that can withstand high voltages to prevent damage from sudden surges.

These devices are non-isolated DC/DC converter ICs developed by utilizing proprietary analogue 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 intended for 24V power supply systems – enabling support for higher functionality and greater miniaturisation 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.
