OB233F
High Performance Current Mode PWM Power Switch
GENERAL DESCRIPTION
OB233F combines a dedicated current mode PWM controller with a high
voltage power
MOSFET.
It is optimized for high performance, low standby power, and cost effective off-line flyback converter applications.
OB233F offers complete protection coverage with automatic recovery feature including Cycle-byCycle current limiting (OCP), over load protection (OLP), over temperature protection (OTP), over
voltage protection and VDD under
voltage lockout (UVLO).
Excellent EMI performance is achieved with On-Bright proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output.
