Datasheet Summary
Description
The OB2269 is a highly integrated currentmode
- Low start-up current and low operating
PWM controller IC for those high output current. power of off line flyback convertor. The output
- prehensive protection functions power is up to 120W.
1 、 Under voltage locked with
OB2269 is integrated start-up circuit that hysteresis (UVLO) on VDD realizes low quiescent dissipation and overload pensation.
J OB2269 has prehenisve protecit onf eature S to ensure reliability of application system. M The packaging of OB2269 has SOP8 and DIP8. I Features
- Digit frequency shuffling technology to O improve EMI performance.
2、Over voltage protection (OVP) on VDD....
