Power stage 5x6
Asymmetric halfbridge handles 30A in a 30mm² footprint
Dual FET power stages in a single leadless SMD package integrate the low
side and high side MOSFET of a synchronous DC/DC converter into a 5x6mm2
package outline. Customers can shrink their design up to 85% by replacing two
seperate discrete packages such as SO-8 or Super SO8 with this new package.
Both the small package outline and the interconnection of the two MOSFETs
within the package minimize the loop inductance which boosts efficiency. With
the new OptiMOS™ technology the power stage 5x6 achieves a peak efficiency
of 93.5% and can handle an application current higher than 30A.
Standardizing power packages benefits the customer as the number of different
package outlines available in the market place is minimized.
Easy and compact layout
