Fast turn-off dual synchronous rectifiers (SR) controller
NEX81915 is a dedicated controller IC for synchronous rectification on the secondary side of resonant converters. It supports operation in discontinuous conduction mode (DCM), continuous conduction mode (CCM) and critical conduction mode (CRM). It has two driver stages for driving the SR MOSFETs. By detecting the Vds of the rectifier, the MOSFETs can be reliably switched on and off, thereby replacing Schottky diodes and improving the efficiency of the resonant converter.
NEX81915 regulates the forward drop voltage of an external synchronous rectifier (SR) MOSFET by decreasing the gate voltage. This allows the SR FET to be turned off quickly when the Vds becomes positive.
NEX81915 is a green and energy-saving product. The turn-on delay time will be increased and the drive current will be decreased to minimize the power consumption at light load. The gate drive will be turned off when the load current reduces to a certain level, thus limiting the IC current to a very low level. The light load efficiency can be improved.
The device is available in SO8 (SOT96-2) package.

How does it work?
The interactive datasheets are based on the Nexperia MOSFET precision electrothermal models. With our interactive datasheets you can simply specify your own conditions interactively. Start by changing the values of the conditions. You can do this by using the sliders in the condition fields. By dragging the sliders you will see how the MOSFET will perform at the new conditions set.
