SRK2000A Description
The SRK2000A smart driver implements a control scheme specific to 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 driving one or more N-channel Power MOSFETs. Each gate driver is controlled separately and an interlocking logic circuit prevents the...
