Description
General part information
SRK2001A Series
The SRK2001A 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 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 driver high-level voltage is clamped to 11 V in order to avoid delivering excessive gate charge to the SR MOSFET when the device is supplied at higher VCC voltages.
