OB2333
Overview
- Level 5 compliance with < 100mW standby PWM controller with a high voltage power power at universal AC input MOSFET. It is optimized for high performance, low
- Power on soft start reducing MOSFET Vds standby power, and cost effective off-line flyback stress converter applications in sub 8W range.
- Frequency shuffling for EMI OB2333 offers complete protection coverage with
- Extended burst mode control for improved automatic self-recovery feature including Cycle- efficiency and minimum standby power design by-Cycle current limiting (OCP), over load
- Audio noise free operation protection (OLP), over temperature protection
- Fixed 55KHZ (typical) switching frequency (OTP), over voltage protection and VDD under
- Internal synchronized slope compensation voltage lockout (UVLO). Excellent EMI
- Low VDD startup current and low operating performance is achieved with On-Bright current proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output. to The tone energy at below 20KHZ is minimized in the design and audio noise is eliminated during l operation. OB2333 is offered in SOP8 package. tia APPLICATIONS Offline AC/DC flyback converter for n
