Product Information
Product Overview
LT3599 is a fixed frequency 2A step-up DC/DC converter designed to drive four strings of 120mA LEDs upto a 44V output voltage. LED dimming can be achieved with analog dimming on the CTRL pin, and with pulse width modulation dimming on the PWM pin. This device accurately regulates LED current even when the input voltage is higher than the LED output voltage. It is widely used in application such as automotive navigation TFT LCD displays, desktop and notebook TFT LCD displays etc.
- True colour PWMTM dimming ratio upto 3000:1
- ±1.5% accurate LED current matching
- Wide input voltage range is 3.1V to 30V
- Regulates LED current even when VIN <gt/> VOUT
- Disconnects LEDs in shutdown, analog dimming upto 20:1
- Programmable maximum VOUT (regulated)
- Open/short LED protection and fault flags
- Adjustable frequency is 200KHz to 2.1MHz
- Synchronizable to an external clock, programmable input UVLO with hysteresis
- Operating temperature is -40°C to 125°C, packaging style is 28-lead plastic TSSOP
