Frequently Asked Questions
What input voltage range does the LT3791EFE-1#PBF support, and what conversion topology does it use?
The LT3791EFE-1#PBF operates over a wide 4.7 V to 60 V input range and uses a current-mode PWM buck-boost topology, allowing it to regulate output voltage smoothly whether the input is above, equal to, or below the target output level.
How does the 700 kHz switching frequency of LT3791EFE-1#PBF benefit a compact power supply design?
Operating at 700 kHz allows the LT3791EFE-1#PBF to use smaller inductors and filter capacitors compared to lower-frequency controllers, reducing PCB footprint and bill-of-materials cost. The high switching frequency also improves transient response speed for dynamic loads up to 10 A.
Is LT3791EFE-1#PBF a suitable controller for automotive LED driver designs?
Yes, the LT3791EFE-1#PBF is an excellent fit for automotive LED drivers because its 4.7 V to 60 V input range accommodates cold-crank and load-dump conditions in 12 V and 24 V vehicle systems. The TSSOP-38 package and 10 A output capacity allow efficient high-power LED string driving in a compact footprint.
