Isolated 2.5-W SiC & IGBT gate-drive reference design with integrated switch PSR flyback converter
Description
This reference design provides two isolated voltages from a 24-V DC input supply. By means of zero ohm resistors: it is possible to configure the two independent outputs as +15 V and +4 V: or +15 V and -4 V with common ground with a total power of 2.5 W. The integration of a 100-V rated primary-side switch: together with the elimination of an auxiliary winding in the transformer: enables a compact solution.
