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 ...

Analog Devices Inc. (ADI) introduces the ADP2119 and ADP2120 dc-to-dc switching regulators. The highly integrated 2 A/1.25 A, step-down, dc-to-dc synchronous regulators include low on-resistance ...
