DESCRIPTION
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’ specifica-
tions 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 V OUT 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 cur-
rent and programmable temperature protection.
