Description

This reference design is a 3-kW, two-phase, interleaved half-bridge inductor-inductor-capacitor (LLC) using the LMG3422 and F280039C devices. The design can achieve 98.1% peak efficiency and 313 W / in3 power density. This design can be used as the output stage of a common redundant power supply (CRPS) server power supply and can be used to evaluate the control method for two paralleled LLC stages, such as interleaving and current balance.
