Anwendungshinweise
- Gate Driver Design ConsiderationsPDF, 229 Kb, Datei veröffentlicht: Oct 10, 2016
The UCC28950/UCC28951-Q1 phase-shifted full-bridge controllers offer several features to improve power conversion efficiency at light loads. In particular, as the load current drops below the DCM threshold the duty cycle applied to the transformer reduces and eventually the device enters a burst mode. This application note describes how a user can design their gate driver circuits to operate corre
