AXElite AX6224
AX6224 is offered in SOP-8L package. The PWM duty cycle is determined by voltage level into this pin and the current-sense signal at Pin 4. AX6224 offers complete 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).GENERAL DESCRIPTION
AX6224 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 under 8W range. Excellent EMI performance is achieved with 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. AX6224 is offered in SOP-8L package. FEATURES
