Additional Infomation About Product

AN3303 Application note Secondary-side rectification for LLC resonant converter featuring SRK2000 Silvio De Simone Introduction The EVLSRK2000 is a family of demonstration boards designed for the evaluation of the SRK2000 in LLC resonant converters with synchronous rectification (SR). The first part of this application note is a brief description of the IC features while the second is dedicated to the board description. Finally, some considerations regarding circuit optimization and performance are given. This board was realized in four different configurations depending on the mounted SR MOSFETs. Different board codes are shown in Table 1: Table 1.
