Asymmetric half-bridge MOSFET solution handles 50 A in a 30 mm² footprint
OptiMOS™ 5 power block is a leadless SMD 5.0 x 6.0 mm² small outline package, integrating a low-side and a high-side MOSFET targeting synchronous rectification buck converter applications. By replacing two separate discrete packages, such as SO8 or SuperSO8, with the space-saving MOSFET package, OptiMOS™ 5 power block 5 x 6 customers can shrink their designs by at least 50%. Standardizing power packages benefits the customer, as the number of different package outlines available on the marketplace is minimized.
Benchmark efficiency and high current handling
The MOSFET half-bridge family features Infineon’s proven OptiMOS™ 5 technology, which offers low on-state resistance (RDS(on)) and figure of merits (Qg, Qgd). The source-down connection of the low-side MOSFET results in a big PGND pad which significantly improves the thermal junction to the board, simplifying the layout and reducing EMI. This solution allows engineers to optimize their designs by increasing switching frequency and power density as well as reducing overall BOM costs.
