LT3596 - Linear Technology

LT3596 60V Step-Down LED Driver

The LT®3596 is a 60V step-down LED Driver. It achieves 10,000:1 digital PWM dimming at 100Hz with fast NPN current sources driving up to 10 LEDs in each channel. 100:1 LED dimming can also be done with analog control of the CTRL1-3 pin. The step-down switching frequency is programmable between 200kHz and 1MHz and is synchronizable to an external clock. The L.
