Frequently Asked Questions
What input voltage range does the LT3759IMSE#TRPBF support for automotive applications?
The LT3759IMSE#TRPBF supports an input voltage range of 1.6 V to 42 V, making it suitable for automotive 12 V and 24 V battery systems, including cold-crank conditions down to 1.6 V and load-dump transients up to 42 V.
At what switching frequency does the LT3759IMSE#TRPBF operate and how does it affect design size?
Operating at up to 1000 kHz, the LT3759IMSE#TRPBF allows designers to use smaller inductors and output capacitors, reducing overall PCB area. This high frequency is critical for compact automotive power modules where board space under 10 cm² is often required.
When is the LT3759IMSE#TRPBF preferred over a lower-frequency boost controller in a motor-control system?
In motor-control systems requiring tight ripple regulation and compact magnetics, the LT3759 at 1000 kHz switching outperforms 200-400 kHz controllers by reducing inductor size by up to 5x and enabling ceramic output capacitors, simplifying the BOM for 12-pin MSOP footprint designs.
How does the MSOP-EP package of the LT3759IMSE#TRPBF improve thermal performance?
The 12-pin MSOP-EP exposed pad allows direct thermal contact to the PCB ground plane, reducing junction-to-board thermal resistance. This enables higher continuous power dissipation compared to standard MSOP packages without an EP, typically improving thermal headroom by several degrees Celsius per watt.
