General Description
CR622X 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 24W range. CR622X 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. CR622X is offered in DIP-8L & SOP-8L package.
