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 ...

We often use linear regulators in our designs. They are cheap and simple – you put the regulator chip itself on the board, add two capacitors, and get a voltage. Linear regulators are imperfect, 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 ...
