Frequently Asked Questions
What is the input voltage range of the LTC3637EMSE#TRPBF, and which industrial bus voltages does it support?
The LTC3637EMSE#TRPBF accepts input voltages from 4 V to 76 V, covering 12 V, 24 V, and 48 V industrial bus standards. This wide range eliminates the need for a pre-regulator in most factory-automation and transportation designs.
How does burst-mode control in the LTC3637EMSE#TRPBF improve efficiency at light loads compared to fixed-frequency operation?
Burst-mode control reduces switching losses by turning off the power switch during low-load intervals, which keeps quiescent current low—typically under 100 µA—compared to fixed-frequency operation that switches continuously and dissipates more energy regardless of load.
For a 48 V automotive supply design, what output voltage options does the LTC3637EMSE#TRPBF offer?
From a 48 V rail, the LTC3637EMSE#TRPBF can supply a fixed 3.3 V or 5 V output, or any adjustable voltage from 0.8 V to 76 V at up to 1 A, enabling a single regulator IC to power multiple downstream loads.
