LT3478 17W, 15 LEDs at 350mA, Boost LED Driver plus LT3003

Sep 9th 2016
The LT3478-1 reduces external component count and cost by integrating the LED current sense resistor. The LT3478 uses an external sense resistor to extend the maximum programmable LED current beyond 1A and also to achieve greater accuracy when programming low LED currents. Operating frequency can be set with an external resistor ...

LT3965 Matrix LED Dimmer Powered by a Dual Buck Mode LED Driver with a Boost Pre-Regulator

Sep 2nd 2016
The LT®3965 is an LED bypass switching device for dimming individual LEDs in a string using a common current source. It features eight individually controlled floating source 17V/330mΩ NMOS switches. The eight switches can be connected in parallel and/or in series to bypass current around one or more LEDs in a string. ...
