OB2358AP - DIP

OB2358 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 in sub 27W range. OB2358 offers complete protection coverage with automatic self-recovery features including Cycle-by-Cycle current limiting (OCP), overload 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 20 KHZ is minimized in the design and audio noise is eliminated during operation. OB2358 is offered in the DIP8 package.
