**LT1935ES5#TRMPBF: A 2MHz Boost Converter in SOT-23 Package for Compact Power Solutions**

The relentless drive towards miniaturization in modern electronics demands power management solutions that are not only efficient but also exceptionally space-conscious. Addressing this critical need, the **LT1935ES5#TRMPBF** from Analog Devices stands out as a high-performance, monolithic boost converter that integrates a **2MHz fixed-frequency switching regulator** into a minuscule **SOT-23 package**. This combination of high speed and ultra-compact form factor makes it an ideal cornerstone for a wide array of portable and compact applications.

At the heart of this device's appeal is its ability to **minimize the footprint of the entire power supply circuit**. The high 2MHz switching frequency allows for the use of tiny, low-profile surface-mount inductors and capacitors. This drastically reduces the required board space, which is often dominated by these passive components. Designers can thus achieve a complete boost converter solution that occupies a remarkably small area, a vital advantage in space-constrained devices like smartphones, wearable health monitors, and compact sensor modules.

Despite its small size, the LT1935ES5#TRMPBF does not compromise on performance or flexibility. It features an integrated **1.5A, 36V power switch**, enabling it to efficiently generate higher output voltages from a low input supply. With an input voltage range starting as low as **2.6V**, it is perfectly suited for single and dual-cell lithium-ion battery applications or for generating standard voltage rails like 12V or 5V from a 3.3V supply. Its current-mode architecture ensures excellent line and load regulation and provides a fast transient response to sudden changes in load current.

The device incorporates essential protection features to enhance system reliability. These include **soft-start functionality** to limit inrush current during startup and frequency foldback to prevent inductor current runaway when the output is short-circuited. Its design ensures robust operation across a wide temperature range, making it suitable for industrial and automotive environments as well as consumer products.

**ICGOOODFIND**: The LT1935ES5#TRMPBF is a quintessential component for modern power design, masterfully balancing high performance with minimal size. Its high switching frequency and integrated switch in a SOT-23 package empower engineers to create efficient and reliable power solutions for the next generation of portable and compact electronic devices, where every square millimeter of PCB space is precious.
