Onboard DC/DC Buck Converter

As a key component in the power supply system of new energy vehicles, the DC/DC buck converter is responsible for stepping down the high-voltage DC output from the power battery to provide low-voltage DC output for various loads in electric vehicles. It also charges the 12V/24V auxiliary battery. The converter is controlled by the main controller to ensure stable voltage, high conversion efficiency, and reliability. It also features protection functions such as input over/under voltage protection, output over/under voltage protection, output short circuit protection, input reverse connection protection, and over-temperature protection.
