LOW-POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
Solutions for Power Supply Applications
The growing deployment of navigation, entertainment and
communication equipment in modern cars, as well as the
utilization of most advanced semiconductor technologies,
has been changing the needs for voltage regulation in
the car. Automotive power supplies are used for DC-DC
conversion, DC voltage monitoring, pulse-width modulation
and digital control. Electronic Control Units are using
SEPIC and Buck Converters with multiple level output
voltages and different current ratings.
