OB2269
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 Comprehensive 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 compensation.
Key Features
- Digit frequency shuffling technology to O improve EMI performance. 2、Over voltage protection (OVP) on VDD. 3、Cycle-by-Cycle current limitation 4、Over load protection (OLP) 5、Over temperature protection (OTP)
- Current limitation compensation to obtain the same output current in * * *
- External programmable PWM switching frequency. S Leading edge Blanking on current sense e input. m Internal synchronized slope i compensation . c Burst mode control to improve efficiency onductor and optimize standby power consumption. universal AC line input.
- 800mA Drive Capability
