Product Brief OptiMOS™ 5 25 V Power Block Asymmetric Halfbridge Handles 50 A in a 30 mm2 Footprint OptiMOS™ 5 Power Block is a leadless SMD package in a 5.0x6.0 mm² package outline, including a low-side and a high-side MOSFET in a synchronous buck converter configuration. By replacing two separate discrete packages, such as SO8 or SuperSO8, with the OptiMOS™ 5 Power Block, customers can shrink their designs up to 85%. Standardizing power packages benefits the customer, as the number of different package outlines available in the market place is minimized. Main Features 50 A max. average load current Source-down low-side MOSFET for better PCB cooling Internally connected low-side and high-side (lowest loop inductance) Benchmark Efficiency and High Current Handling OptiMOS™ 5 Power Block features Infineon’s latest generation MOSFETs, which offer lowest 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, simplifies layout options and reduces EMI. Together with OptiMOS™ Driver (PX3519, PX3517) and Controller family, Infineon offers an excellent discrete solution for low voltage DC/DC power conversion with a current handling up to 50 A and a superior peak efficiency of 95%. This solution allows engineers to optimize their designs by increasing switching frequency and power density as well as to improve the overall BOM costs.
