Power Density Considerations

In the power converter market where these half-bridge gate drivers are utilized, space and weight are often constrained despite the elevated power levels that are required. Gate drivers that feature small outline packages and incorporate thermal pads for increased heat dissipation are advantageous within these design constraints. This size constraint is excellent in multiphase systems where multiple gate driver circuits occupy circuit board space and the typical application requires high power. For high current, the UCC273x1A(-Q1) is offered in a 3mm by 3mm DRC package that is of SON type and is a 120V half-bridge driver. The UCC273x1A(-Q1) has peak drive current ratings of 3.7A source and 4.5A sink. This DRC package is the smallest package currently offered in the high current 120V half-bridge portfolio and includes the enable pin optimizing this driver to be disabled in multiphase converter operation. For lower current and less power dense applications, a 3A source and sink current 120V driver can potentially be used. When operated in single phase converter configurations, the UCC2728x(-Q1) can be used and is also offered in the small DRC package and features enable.
