LT3791IFE Overview


In order to save board space, the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package is used. A LED driver with 1 outputs is designed.Surface Mount represents this mounting method.With high reliability and efficiency, this emerges as a DC DC Controller.It is possible for the led driver ic to function normally at -40°C~125°C TJ.The benefits of Automotive, Lighting are considerable.On the basis of the frequency 200kHz~700kHz, it operates.It is designed to work with 38 terminations.If the voltage supply is less than 4.7V, undetermined failures will occur.The voltage output by it is 0V~60V.38 pins are used on the device.This device is optimized to deliver a maximum voltage level of 60V.There are many applications for this LED driver belonging to the True Color PWM? series.5V is the voltage at the output terminal.When operating the device, 12V volts are assigned to the circuit.The device operates much more conveniently when the input voltage exceeds or equals 4.7V.The input voltage should be kept below 60V to ensure high stability.
