Power Solution for 450W Automotive Audio Amplifier (PMP7837)

The PMP7837 is a 4-phase synchronous boost converter that can take a 6-17V input and put out 24V at 450W. It is used for powering up to eight 50W automotive trunk amplifiers. The 4-phase synchronous design with 450kHz switching frequency per phase results in a compact and efficient circuit well suited for such applications.
