LT1372CS8#TRPBF

Overview

The LT1372CS8#TRPBF is a high-efficiency switching regulator IC from Analog Devices, designed for versatile DC-DC conversion topologies including buck, boost, Cuk, flyback, forward, and inverting configurations. It operates with an input voltage range of 2.7V to 30V and delivers a switch current of 1.5A. The device features an adjustable output starting at 1.245V, supporting both positive and negative output polarities. Operating at a fixed switching frequency of 500kHz, it utilizes an 8-SOIC surface-mount package and functions within a junction temperature range of -40°C to 125°C.

Feature Summary

• Supports multiple converter topologies including buck, boost, Cuk, flyback, forward, and inverting circuits
• Provides adjustable output voltage with support for both positive and negative polarity configurations
• Integrates a 1.5A internal switch capable of handling wide input voltage ranges up to 30V

Applications

• Buck and boost power supply designs requiring flexible topology selection
• Negative voltage generation circuits using inverting or Cuk configurations
• Isolated power supplies utilizing flyback or forward transformer-based architectures

Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging and commercial grade temperature rating. Ensure the ordering part number matches the exact electrical specifications required for your design, as variations exist within the LT1372 family. Cross-reference the datasheet revision date to guarantee compatibility with your schematic and layout requirements.

Selection Notes

Select this component when a single IC must support diverse conversion topologies such as buck, boost, or isolated flyback applications. It is suitable for designs requiring an adjustable output voltage with either positive or negative polarity. Consider the 500kHz switching frequency and 1.5A switch current capability relative to your inductor selection and thermal management constraints.

Part Context

This part belongs to the LT1372 series of high-efficiency switching regulators manufactured by Analog Devices Inc. The series is characterized by its ability to implement various standard DC-DC converter topologies using minimal external components. The CS8 suffix indicates a commercial temperature range variant housed in an 8-pin SOIC package, distinguishing it from other temperature grades or package options available in the broader product line.
