Product Overview

The LT3791HFE#PBF is a synchronous 4-switch buck-boost LED Driver Controller can regulate LED current up to 52V of LED string with input voltages above, below or equal to the output voltage. The constant-frequency, forced-continuous current mode architecture allows its frequency to be adjusted or synchronized from 200 to 700kHz. No top MOSFET refresh switching cycle is needed in buck or boost operation. With 60V input, 60V output capability and seamless transitions between operating regions. The LT3791 provides input current monitor, LED current monitor and open or shorted LED fault condition, during which the LT3791 either restarts or latches off.
  • Synchronous switching - Up to 98.5% efficiency
  • True Colour PWM™ and analogue dimming
  • LED and input current regulation with current monitor outputs
  • VOUT Disconnected from VIN during shutdown
  • Open or shorted LED fault protection
  • Capable of 100W or greater per IC
