LT1930ES5#TRMPBF

Overview

The LT1930ES5#TRMPBF is a DC-DC switching regulator IC manufactured by Analog Devices Inc., designed for high-efficiency power conversion in compact applications. It operates with an input voltage range of 2.45V to 16V and provides a single adjustable output configuration capable of reaching up to 36V. The device integrates a 1A switch and supports multiple topologies including boost, flyback, and SEPIC. Operating at a fixed switching frequency of 1.2MHz, it utilizes a TSOT-23-5 package suitable for surface mount installation within a temperature range of 0°C to 70°C.

Feature Summary

• Integrates a high-voltage internal switch enabling generation of high output voltages from low input sources
• Supports versatile circuit configurations including step-up, isolated flyback, and non-inverting SEPIC topologies
• Utilizes a high switching frequency to minimize the physical size of external passive components

Applications

• Portable battery-powered equipment requiring efficient voltage boosting
• Industrial control systems utilizing isolated power supply architectures
• Embedded sensor networks needing compact non-inverting buck-boost regulation

Procurement Notes

Verify that the specific suffix #TRMPBF corresponds to the Tape and Reel packaging format required for automated assembly processes. Confirm that the ES5 grade meets the operational temperature requirements for your specific application environment. Ensure compatibility with standard SMT reflow profiles for the TSOT-23-5 package during manufacturing integration.

Selection Notes

Select this component when design constraints demand a small footprint combined with moderate current capabilities. The 1.2MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the LT1930AES5 variant if a higher switching frequency is necessary to further reduce passive component volume. Evaluate thermal dissipation requirements based on the selected topology and load conditions.

Part Context

This part belongs to the LT1930 family of switching regulators, which are characterized by their ability to deliver significant power in minimal space. The series includes variants like the LT1930A offering higher frequencies. These devices are positioned as solutions for applications where board area is limited but robust power management is essential, bridging the gap between simple linear regulators and larger discrete switching solutions.

Replacement Considerations

The LT1930AES5#TRMPBF serves as a direct functional substitute within the same family, differing primarily in switching frequency specifications.
