1 / 5
Designed to provide 48V to 12V power conversion for heavy-duty applications, the DC/DC converter offers reliable system performance and flexibility. The converter uses two buck power stages in parallel. The multiphase buck converter architecture uses interleaved timing to multiply power stage ripple frequency and reduce input and output ripple currents. It provides a fixed output to power 12V loads directly from a 56V or 48V source.
