DC/DC Converters and Charging

You need high frequency and high isolation for your high side applications. We have it. Check out our 1MHz current sensor ICs with lightning fast response time to reduce your overall BOM cost and PCB area, while increasing quality in your DC/DC converters. These devices are perfect replacements for your bulky current transformers.

Did you know Allegro was first to market with the popular 100uOhm CB package? Check out what else we have to offer for your charging applications.
