AEC-Q100 DC/DC Converters Allow Migration from 3A to 5A Without PCB Change

Renesas' ISL78233/34/35 automotive DC/DC converters step-down 5V rails to POL for GPUs, FPGAs, DSPs and SOCs. The highly efficient devices deliver 3A, 4A and 5A of continuous output current to infotainment head units and Advanced Driver Assistance Systems (ADAS) employing forward-looking smart cameras to detect and classify objects.

The pin-compatible ISL78233/34/35 ICs allow you to make a simple BOM change and drop in the right device to your PCB to address the varying load requirements of entry-level to luxury car models.
