Its 91% efficiency and superior thermal performance make the Veta™
Family of power modules ideally suited for power-hungry applications in
demanding thermal environments. This rugged building block is
designed to serve as the core of your high reliability system. A wide
output voltage trim range, -46 to +10%, and remote sensing are
standard features enhancing versatility. For a full-featured version of the
Veta™ Half Brick, including active current sharing, see the iHD product
brief.
