Frequently Asked Questions
What is the input voltage range that LTC3631EMS8E#TRPBF can handle?
The LTC3631EMS8E#TRPBF accepts an input voltage from 4.5 V to 45 V, enabling it to operate directly from automotive 12 V or 24 V battery rails as well as industrial 36 V bus supplies without an additional pre-regulator stage.
How low can the output voltage be set on the LTC3631EMS8E#TRPBF, and what limits that minimum?
The adjustable output can be set as low as 0.8 V using an external resistor divider. The minimum is set by the internal 0.8 V reference, allowing the device to power modern DSP cores and FPGAs that require sub-1 V supply rails with up to 100 mA load current.
Which automotive and industrial designs benefit most from the LTC3631EMS8E#TRPBF in the 8-pin MSOP-EP package?
Applications that combine a harsh 45 V bus with tight board space gain the most — for example, ECU sensor power supplies, telematics modules, and 24 V PLC auxiliary rails. The 8-pin MSOP-EP package occupies roughly 5 mm × 3 mm of PCB area, and the exposed pad improves thermal dissipation at 100 mA output current.
