description

LT^®The 3599 is a fixed frequency, 2A step-up DC/DCconverter, designed to drive four strings of 120mA LEDs with an output voltage up to 44V. The switching frequency can be programmed from 200kHz to 2.1MHz with an external resistor.

The LED dimming function can be implemented using analog dimming circuitry on the CTRL pin and pulse-width modulation dimming circuitry on the PWM pin. The LT3599 accurately regulates LED current, even when the input voltage is higher than the LED output voltage.

Other features include programmable LED current derating, switching frequency synchronization to an external clock, LED string disable control,OPENLEDAlarm pins,SHORTLEDProgrammable maximum output voltage for alarm pins and when all LED strings are disconnected. The LT3599 is available in thermally enhanced 32-lead (5mm × 5mm) QFN and 28-lead TSSOP packages
