Datasheet Details

Part number	U6205DC
Manufacturer	UNI SEMI
File Size	1.27 MB
Description	Offline Current Mode PWM Power Switch
Datasheet	U6205DC U6202SC Datasheet (PDF)

U620XC is a high performance current mode PWM power switch for offline flyback converter applications.

The IC has built-in General Primary Side CC control, which simplifies isolated power supply design that requires CC regulation of the output.

In U620XC, PWM switching frequency with shuffling is fixed to 65KHz and is trimmed to tight range.
