The paper deals with proposal and simulations of the high efficiency and high-power switching power supply suited for hi-fi audio amplifiers in automotive applications. Main focus is given on specific requirements, which are needed in the automotive segment, low voltage input must be considered. The presented article describes design of the main topology and its parameters. Key operational characteristics are very high efficiency in full spectrum of operation and high-power density. The performance of proposed design is condition by high-current operation, thus thermal management is key indicator related to requirements on high-efficiency operation. Secondary features of proposed converter must consider high-end requirements of audio systems, which are fast dynamics to load change and low noise of output voltage. Almost switched-mode power supplies are defined by high noise of the output voltage, presented approach proposes also solution of the low noise output filter.
