Overview
The LT1372CS8#TRMPBF is a monolithic high-frequency switching regulator manufactured by Analog Devices Inc. It operates at switching frequencies of 500kHz or 1MHz and delivers a switch current of 1.5A. The device supports multiple topologies including boost, buck, flyback, forward, inverting, Cuk, and SEPIC configurations. It accepts an input voltage range from 2.7V to 30V and provides an adjustable output voltage starting from 1.245V up to 35V. The component is housed in an 8-SOIC package with a maximum junction temperature rating of 125°C.
Feature Summary
- Supports versatile DC-DC conversion topologies including boost, buck, flyback, forward, inverting, Cuk, and SEPIC within a single integrated circuit.
- Integrates a high-efficiency 1.5A power switch along with complete oscillator, control, and protection circuitry on the die.
- Enables flexible power design through adjustable output voltage capabilities and operation across wide input voltage ranges.
Applications
- Lithium-ion battery powered systems requiring step-up or SEPIC conversion
- General purpose DC-DC power supply designs utilizing standard switching configurations
- Embedded applications needing compact high-frequency regulation solutions
Procurement Notes
Verify the specific suffix #TRMPBF indicates tape-and-reel packaging when sourcing components. Confirm the operating frequency configuration matches system requirements as the device supports both 500kHz and 1MHz options. Ensure thermal management aligns with the specified junction temperature limits for the target application environment.
Selection Notes
Select this component for designs requiring a single IC to support multiple converter topologies without external power switches. Consider the 1.5A switch current limit and 30V maximum input voltage when defining power boundaries. Evaluate the 8-SOIC package constraints against available PCB real estate and thermal dissipation needs.
Part Context
This part belongs to the LT1372 family of high-efficiency switching regulators from Analog Devices. It shares core architecture with variants like LT1372IS8 but differs in packaging and reel specifications. The series is designed for applications demanding flexibility in topology selection while maintaining high efficiency at standard switching frequencies.
Replacement Considerations
LT1372IS8#PBF offers identical electrical performance in an SOIC-8 tube package instead of tape-and-reel. LT1372CN8 provides the same functionality in a DIP-8 package for through-hole applications. Verify pinout compatibility and thermal characteristics when substituting these variants.
