CRE6354

Current Mode PWM Power Switch CRE6354 Freq Shuffling Product Specification GENERAL DESCRIPTION FEATURES CRE6354 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 20W range. ■ Power on Soft Start Reducing MOSFET Vds Stress ■ Frequency shuffling for EMI ■ Extended Burst Mode Control For Improved Efficiency and Minimum Standby Power Design ■ Audio Noise Free Operation ■ Fixed 50KHZ Switching Frequency CRE6354 offers complete protection coverage with ■ Internal Synchronized Slope Compensation automatic self-recovery feature including Cycle-by-Cycle ■ Low VDD Startup Current and Low Operating Current current limiting (OCP), over load protection (OLP), VDD over voltage clamp and under voltage lockout (UVLO). Excellent EMI performance is achieved with PowerSource proprietary frequency shuffling technique together with soft switching control at the totem pole gate drive output. ■ Leading Edge Blanking on Current Sense Input ■ Good Protection Coverage With Auto Self-Recovery  VDD Over Voltage Clamp and Under Voltage Lockout with Hysteresis (UVLO)  On-Bright Proprietary Line Input Compensated Cycle-by-Cycle Over-current Threshold Setting For Constant Output Power Limiting Over The tone energy at below 20KHZ is minimized in the Universal Input Voltage Range. design and audio noise is eliminated during operation.
