LT3950 Datasheet (Analog Devices)

LT3950, 1.5A LED Driver

The LT®3950 is a multitopology DC/DC converter designed specifically to drive high current LEDs.

It contains a 1.5A, 60V DMOS switch and supports an external PWM dimming PMOS.

The LT3950 has an internal PWM generator for dimming that maps an analog control signal to an exponential scale used to defi
