OB2358
DESCRIPTION
OB2358 bines 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 in sub 27W range. OB2358 offers plete protection coverage with automatic self-recovery feature including Cycle-by Cycle current limiting (OCP), over load protection (OLP), VDD over voltage clamp and 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. .. The tone energy at below 20KHZ is minimized in the design and audio noise is eliminated during operation. OB2358 is offered in DIP8 package.
