Thanks to its high performance drivers and versatility, it can be used in various topologies such as DCM or CCM flyback, quasi resonant flyback, forward and half bridge resonant LLC. The combination of externally adjustable minimum off-time and on-time blanking periods helps to fight the ringing induced by the PCB layout and other parasitic elements. A reliable and noise less operation of the SR system is insured due to the Self Synchronization feature.Precise True Secondary Zero Current Detection with Adjustable Threshold Typically 20 ns Turn off Delay from Current Sense Input to Driver Zero Current Detection Pin Capability Adjustable Minimum ON Time and Minimum OFF Time Self Synchronization Light Load Detection with Modulated Gate Drive Improves performance for applications working in deep CCM Enters the IC into a low consumption standby mode
