LOW-POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
Solutions for LED Applications
Traditional incandescent lamps are increasingly being
replaced by Light Emitting Diodes (LEDs). LEDs offer
compelling advantages, including a high level of light
efficiency, reliability, mechanical stability and long
operating lifetime. Because LEDs must be operated at
constant current, DC-DC converters with the capability of
efficiently translating the operating voltage into the LED
forward voltage are required. Further key elements of LED
control circuits are overcurrent protection, over heating
A typical LED solution can be as simple as a battery and
a resistor, but with more complex dimming, flashing and
multi-color applications; and more rigorous requirements
in terms of matching brightness and color, there is an
increasing need to control and monitor the current in an
LED application.
