LT3590 48V Buck Mode LED Driver in SC70 and 2mm x 2mm DFN DESCRIPTION
The LT®3590 is a fixed frequency buck mode converter specifically designed to drive up to 10 LEDs in series from a 48V DC source.
Series connection of the LEDs provides identical LED currents of up to 50mA, resulting in uniform brightness and eliminating the need for ballast resistors.
A fixed frequency, current mode architecture results in stable operation over a wide range of input
voltage and output
voltage.
The high switching frequency of 850kHz permits the use of tiny, low profile inductors and
capacitors.
A single pin performs both shutdown and accurate LED dimming...
