Abstract
This paper presents an LLC resonant DC-DC converter suitable for low voltage applications. The circuit, designed and simulated in a standard 180-nm BCD process, employs a MOSFET-based active rectifier in order to minimize conduction losses, thus increasing the efficiency at heavy load. The circuit operates with an input voltage of 5 V (±10%), an output voltage of 12 V, and provides to the output a maximum power of 2 W. Transistor level simulation results show an efficiency of 84% at full output power.
