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 LT3596 also provides maximum LED brightness while adhering to manufacturers’ specifications for thermal derating. The derate temperature is programmed by placing a negative temperature coefficient (NTC) resistor on the master control pin.
The LT3596 adaptively controls VOUT in order to achieve optimal efficiency. Other features include: 1.5% LED current matching between channels, open LED reporting, shorted LED pin protection and reporting, programmable LED current and programmable temperature protection.
