As their production costs fall, LEDs are being used more often in applications ranging from handheld devices to automotive and architectural lighting. Their high reliability (operational lifetimes of ...

Using a switching regulator as an LED driver requires the designer to convert a voltage regulator into a current regulator. Beyond the challenge of changing the feedback system to control current, the ...

A buck-boost controller IC with four external switching MOSFETs can operate from input voltages above, below, or equal to the output voltage, enabling them to regulate the light output for a string of ...

To maximize system efficiency, buck regulators minimize power loss in the switching MOSFETs, inductor, capacitors, controller, and printed circuit board traces. Fairchild’s TinyBuck® family of ...
