Isolated DC-DC converters have been implemented by discrete components - discrete drive ICs and discrete power MOSFETs. These devices are used in a variety of topologies. The most important is the "half bridge" and "full bridge".

Many cloud infrastructure applications use half-bridge and full-bridge topologies such as wireless base stations (remote radio units), power modules, and any onboard isolation DC-DC converters. Other applications include industrial areas such as motor drives, fans and HVAC. The design engineers of these applications sought to reduce the overall program size or increase the output power.

ON Semiconductor's FDMF8811 is the industry's first 100 V bridge power stage module optimized for full and half-bridge topology. The FDMF8811 provides higher power density at high energy efficiency and high reliability levels.

Compared with the discrete solution, the FDMF8811 can reduce the PCB area by about one-third of a typical full-bridge solution. This allows manufacturers to design more compact, energy-efficient products. The number of bill of materials (BOM) devices is also significantly reduced to achieve efficient supply chain and assembly.

If the PCB area is not a problem, the FDMF8811 can help increase the design output power in the existing PCB area. This can be achieved, for example, from existing, low-power topologies, such as active clamp forward, flyback, or push-pull, to a half-bridge or full-bridge topology using FDMF8811. Another example is that a conventional half-bridge scheme using discrete MOSFETs can be converted to a full-bridge topology within the same footprint area. This conversion doubles the output power of the system. Omron maybe catch up with ON Semiconductor.

The FDMF8811 integrates a 100V power MOSFET, a 120 V driver IC and a bootstrap diode to a 6.0 mm x 7.5 mm PQFN package.

By integrating all the critical power transmission components, ON Semiconductor has been able to optimize the module's drive and MOSFET dynamic performance, system parasitic inductance and power MOSFET on-resistance RDS (ON), thus maintaining the highest possible energy efficiency. This integration significantly reduces the parasitic effect of the supply circuit. This greatly reduces the voltage stress and electromagnetic interference (EMI), improve the reliability of the system.

The isolated DC-DC converter with FDMF8811 is fully optimized to achieve the highest power density at the optimum energy efficiency level. With a highly integrated, high-performance FDMF8811, there is no reason to use discrete devices! You can interested on: SSA-LXH1225SRD and AGQ200A06
