WS2393BN Product Description Switching Mode Power Supply PWM Controller WS2393BN Features  Low startup current (<5uA)  Low operation current (2.0mA)  0.5mA operation current at no-load  Standby power <75mw  Multi-Mode Operation(PFM,PWM,QR)  Current mode operation  Advanced frequency jittering control  Programmable Bulk Capacitor Description In order to enhance the efficiency performance, the WS2393BN integrates the multi-mode PWM controller, which consists of Quasi-Resonant (QR) PWM control for light load condition and Continue Conduction Mode (CCM) for heavy load condition. For lower standby power consumption and higher energy saving requirement, the IC has the Burst Mode function and very low startup current and operating current.
