Frequently Asked Questions

What input voltage range does the LMR38020SDDAR synchronous buck regulator support?

The LMR38020SDDAR accepts a wide 4.2V to 80V input range and delivers up to 2A of continuous output current, making it suitable for high-voltage industrial buses and 24V nominal automotive power rails.

How does the 8-pin small outline package benefit board-level thermal design?

Housed in an 8-pin small outline package, the LMR38020SDDAR combines a synchronous buck topology with 40uA quiescent current, reducing self-heating and enabling compact layouts for power budgets under 2A.

Which end applications benefit most from the LMR38020SDDAR's low quiescent current?

Systems that run on battery or standby power benefit most, since the 40uA quiescent current combined with a 4.2V to 80V input lets the LMR38020SDDAR maintain a 2A output rail efficiently in always-on metering and telematics designs.
