LT3598 6-String 30mA LED Driver with 1.5% Current Matching DESCRIPTION
The LT®3598 is a fixed frequency step-up DC/DC converter designed to drive up to six strings of LEDs at an output voltage up to 44V. LED dimming can be achieved with analog dimming on the CTRL pin, and with pulse width modulation dimming on the PWM pin. The LT3598 accurately regulates LED current even when the input voltage is higher than the LED output voltage. The switching frequency is programmable from 200kHz to 2.5MHz through an external resistor. Additional Features include programmable overvoltage protection, switching frequency synchronization to an...
