Beschreibung
- Application circuit for the TPS23753A, TPS23754, TPS23756 and TPS23757 are intended for applications that have primary-secondary isolation, because of this they do not contain an internal (control loop) error amplifier. Despite the lack of an internal error amplifier, it may be advantageous to use these parts in applications which do not require isolation due to their mix of features. These features include adapter ORing support, 12V supply operation, wider duty cycle, and multiple gate drivers. This Application Report shows how to use the common TLV431 as an error amplifier in conjunction with the this family of parts in a non-isolated flyback converter application
