The LV side of the CLLLC converter is designed in full-bridge configuration. The full-bridge requires twice as many switches as the half-bridge.
LMG2100R044 is used for this stage due to low0output capacitance and good switching performance. The device is supposed to work in soft switching and has no significant turn-on losses.
Resonant capacitors experience high RMS current and need to have small Equivalent Series Resistance (ESR). Also these capacitors are part of the resonant tank and need to have stable characteristics. For the resonant tank, high performance NP0 dielectric type capacitors were used.
