Webepitaxial growth is typically accomplished using an off-axis substrate orientation (4° off-axis in the {11-20} direction) such that step-flow growth dominates [6]. The development of quality power MOSFET devices has been dependent on the 4H-SiC crystal quality. As the dominant SiC MOSFET structure is a vertical device, with current flow WebThe UCC3581 provides functions to maximize light load efficiency that are not normally found in PWM controllers. A linear preregulator driver in conjunction with an external depletion mode N-MOSFET provides initial controller power. Once the bootstrap supply is functional, the preregulator is shut down to conserve power.
