Linear Technology (See Analog Devices)Linear Technology Corp. has announced the LT8391 synchronous buck-boost DC/DC LED controller that regulates LED current from input voltages above, below and equal to the output voltage. Its 4- to 60-V input voltage range makes it ideal for automotive, industrial and architectural lighting applications. Output voltage can be set from 0 to 60 V, enabling the driving of a wide range of LEDs in a single string. An internal four-switch buck-boost controller, combined with four external C-channel metal-oxide-semiconductor field-effect transistors, deliver 10 to over 100 W of LED power. ...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra April 2024 IssueVisible Hyperspectral LEDThe COBRA™ HyperSpec Visible from ProPhotonix Limited is an LED light that focuses exclusively on the visible band between 400 and 700 nm.
