Save Space, Minimize Losses, Boost Efficiency



Dual FET power stage in a single leadless SMD package integrates the low side and high side MOSFET of a synchronous DC-DC converter into a 5.0x6.0mm² package outline. Designers are able to shrink their designs up to 85% by replacing two separate discrete packages such as SO8 or SuperSO8 with this new package.

Both, the small outline and the interconnection of the two MOSFETs within the package minimize the loop inductance which boosts efficiency. With the new OptiMOS™ technology power stage 5x6 achieves a peak efficiency of 93.5%. power stage 5x6 can handle an application current up to 30A.
