Linear Technology LT3003: LED ballaster drives 24 LEDs
Dec 26 2006 12:29PM | Permalink |Comments (0) |
Delivering uniform LED brightness, the LT3003 LED ballaster drives three strings of eight LEDs each at a 3%-accurate current matching. Operating on a 3 to 40V input-voltage range, the device drives 24 LEDs at 350 mA each and features a 3000-to-1 dimming capability. The devices operate in buck, boost, and buck-boost modes.Buck-boost mode allows LEDs to return to the input supply in applications with an input supply that varies above and below the output voltage of the LED strings. The LT3003 costs $1.16 (1000).
