Key Features

  • Current-mode PWM control with 2 A switch current enables high-efficiency boost conversion from 2.5 V to 16 V input
  • Compact 5-pin TSOT-23 package occupies minimal board space for space-constrained portable and handheld designs
  • Adjustable output voltage via external resistor divider suits a broad range of boost regulator applications

Applications

The LT1935ES5#TRMPBF is well suited for battery-powered portable devices, handheld instruments, and LED driver circuits where a compact step-up regulator with 2 A switch current and 2.5 V to 16 V input flexibility is required. Its small TSOT-23 footprint is ideal for single-cell to multi-cell Li-ion or alkaline battery boost converters. Industrial and medical portable equipment benefit from the reliable current-mode PWM architecture that maintains regulation across wide load swings.

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.
