Productomschrijving

The NCP4305 is high performance driver tailored to control a synchronous rectification MOSFET in switch mode power supplies. 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
