Frequently Asked Questions
What is the input voltage range supported by the LT3958IUHE#PBF?
The LT3958IUHE#PBF supports an input voltage range of 5 V to 80 V, making it suitable for a wide variety of industrial and automotive power supply applications where input rails can vary significantly.
Which converter topologies can the LT3958IUHE#PBF implement?
This IC supports boost, flyback, SEPIC, and inverting converter topologies, giving designers flexibility to create positive or negative output rails from a single 5 V to 80 V input source.
How does the programmable switching frequency of the LT3958IUHE#PBF benefit PCB design?
The switching frequency is adjustable from 100 kHz to 1 MHz, allowing designers to optimize the trade-off between efficiency and component size. Higher frequencies reduce inductor and capacitor values, saving board space in compact 48-pin-class power modules.
When is the LT3958IUHE#PBF a better choice than a fixed-topology regulator for automotive DC-DC conversion?
In automotive systems where the input bus can range from 12 V to 60 V and multiple output topologies are needed, the LT3958IUHE#PBF eliminates the need for separate ICs by supporting boost, flyback, SEPIC, and inverting modes with current-mode PWM control and less than 1 µA shutdown current.
