Details
| Topologie | Motor Drive |
| Schaltfrequenz | 52-75 kHz |
| IC-Revision | 00 |
Beschreibung
The UCC28881 integrates the controller and a 14-Ω, 700-V power MOSFET into one monolithic device. The device also integrates a high voltage current source, enabling start up and operation directly from the rectified mains voltage. UCC28881 is the same family device of UCC28880, with higher current handling capability.
