Description

This isolated open-loop LLC transformer-driver converter reference design provides four rail outputs. Each output has dual +18-V and –5-V outputs up to 0.5 W for traction inverter applications. The LLC topology allows the transformer to have significant leakage inductance, but a much smaller primary-secondary capacitance, which significantly reduces common-mode current injection through the bias transformer. This reference design offers a high level of integration and high efficiency in a compact form factor. It has passed CISPR 25 class-3 conducted EMI standard.

Features
