ROHM Unveils DC/DC Converter ICs

ROHM has released buck DC/DC converter ICs with built-in MOSFET, BD9G500EFJ-LA and BD9F500QUZ, that support high voltages and currents in factory automation equipment such as PLCs/inverters, and 5G base stations that handle high power.

ROHMROHM, which leverages a vertically integrated production system along with advanced power processes to develop power supply ICs for the industrial market where reliability and long-term supply are just as important as product characteristics, has recently developed DC/DC converter ICs that support higher voltages and currents.

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 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 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.

Application Examples

48V power supply systems (BD9G500EFJ-LA)

  • Servers, charging stations, and power amps for 5G base stations requiring 48V class power input
  • Electric bicycles, power tools, and other applications requiring 48V/60V class power input
  • Home appliances such as Vacuum cleaners, washing machines, and other applications with motors exposed to large surge voltages

24V power supply systems (BD9F500QUZ)

  • Surveillance cameras and factory automation equipment such as PLCs and inverters requiring 24V class power input
  • Power supplies for low voltage control systems, including FPGAs and SoCs installed in various industrial equipment
