DC/DC Converter IC

Our DC DC Converter family contains all the functions needed to create a wide range switch power supply with several output voltages, whereby the supply voltages can be lower or higher than the output voltages.

With Elmos’s switching regulator families, developed in high-voltage CMOS technology, the smooth transition between the different electrical system voltages (14V, 28V, 42V) in the vehicle is facilitated. The small quiescent current and the wide operating voltage and temperature range mean that the components are also of interest in a variety of other applications.
