General Description
CR6228 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. CR6228 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 frequency shuffling technique together with soft switching control at he totem pole gate drive output. The tone energy at below 20 KHz is minimized in the design and audio noise is eliminated during operation. CR6228 is offered in DIP-8L package.
