OB233F
DESCRIPTION
FEATURES
OB233F bines a dedicated current mode
- Standby power lower than 100m W at
PWM controller with a high voltage power universal AC input
MOSFET. It is optimized for high performance, low
- Power on soft start reducing Power MOSFET standby power, and cost effective off-line flyback
Vds stress converter applications.
- Frequency shuffling for EMI
OB233F offers plete protection coverage with
- Extended burst mode control for improved automatic recovery feature including Cycle-by- efficiency and minimum standby power design
Cycle current limiting (OCP), over load protection
- Audio noise free operation
(OLP), over temperature protection (OTP), over
- Fixed 65KHZ (typical) switching frequency voltage protection and VDD under voltage lockout
- Internal synchronized slope pensation
(UVLO). Excellent EMI performance is achieved
- Low VDD startup current and low operating with On-Bright proprietary frequency shuffling current technique together with soft...
