Available in a PDIP 7 or SOT 223 package, the NCP107x offer a high level of integration, including soft start, frequency jittering, short circuit protection, skip

NCP1077 Features

* include: a timer to detect an overload or a short

* circuit event, Overvoltage Protection with auto

* recovery and AC input line voltage detection. For improved standby performance, the connection of an auxiliary winding stops the DSS operation and helps to reduce input power consumption
