Description

General part information

SRK2001 Series

The SRK2001 controller implements a control scheme specific for secondary side synchronous rectification in LLC resonant converters that use a transformer with center tap secondary winding for full wave rectification.

It provides two high current gate drive outputs, each capable of directly driving one or more N-channel power MOSFET. Each gate driver is controlled separately and an interlock logic circuit prevents the two synchronous rectifier MOSFET from conducting simultaneously.

The control scheme ensures that each synchronous rectifier is switched ON as the corresponding half-winding starts conducting and OFF as its current falls to zero.
