Frequently Asked Questions
What is the input voltage range and switch current rating of the LT1935ES5#TRMPBF?
The LT1935ES5#TRMPBF operates from a 2.5 V to 16 V input and provides a 2 A peak switch current for the boost conversion stage. This wide input range makes it compatible with single-cell Li-ion batteries, 3.3 V rails, and 12 V bus inputs across a variety of portable and industrial designs.
For a single-cell Li-ion powered portable device, how suitable is the LT1935ES5#TRMPBF as a 5 V boost regulator?
The LT1935ES5#TRMPBF is well matched to single-cell Li-ion applications: the 2.5 V minimum input covers the cell's discharged threshold of approximately 3.0 V, while the 2 A switch current delivers efficient 5 V output at loads up to several hundred milliamps. The 5-pin TSOT-23 package keeps PCB area under 10 mm².
How does the TSOT-23 package of the LT1935ES5#TRMPBF compare to other common boost converter packages in terms of board space?
The 5-pin TSOT-23 package measures approximately 2.9 mm × 1.6 mm, making it significantly smaller than SO-8 or DFN-8 alternatives that occupy 5 mm × 4 mm or more. This size advantage is critical in wearable and IoT sensor nodes where total regulator solution area must fit within a few square millimeters.
