Overview
The LT1372IS8#TRPBF is a high-efficiency switching regulator IC from Analog Devices, housed in an 8-SOIC surface-mount package. It supports multiple topologies including boost, buck, Cuk, flyback, forward, and SEPIC configurations. The device operates with an input voltage range of 2.7V to 30V and provides a single adjustable output up to 35V with a switch current rating of 1.5A. It functions at a fixed switching frequency of 500kHz and includes shutdown capability. The component is rated for operation between -40°C and +125°C junction temperature.
Feature Summary
- Supports versatile converter topologies such as boost, buck, Cuk, flyback, forward, and SEPIC within a single monolithic IC.
- Features high efficiency switching regulation suitable for battery-powered applications requiring extended runtime.
- Includes a dedicated shutdown pin to minimize quiescent current consumption during standby modes.
Applications
- Battery-powered portable equipment requiring flexible voltage conversion
- Industrial control systems utilizing isolated or non-isolated DC-DC conversion
- Automotive electronics operating within wide input voltage ranges
Procurement Notes
Verify the specific suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the manufacturer part number matches Analog Devices Inc. documentation exactly. Ensure the 8-SOIC package dimensions align with PCB footprint requirements. Validate RoHS compliance status through official material declarations before integration.
Selection Notes
Select this component when design requirements demand a single IC solution for multiple converter topologies rather than discrete implementations. Consider the 1.5A switch current limit and 500kHz frequency for thermal management and passive component sizing. Evaluate the 2.7V minimum input voltage against source availability. Compare against synchronous alternatives if higher efficiency at light loads is critical.
Part Context
This part belongs to the LT1372 family of high-efficiency switching regulators designed by Analog Devices. It serves as a versatile power management solution replacing complex discrete designs. The IS8 variant specifically denotes the 8-pin SOIC package configuration. It complements other linear and switching regulators in the company's portfolio for comprehensive system power architectures.
Replacement Considerations
LT1372IS8#PBF is a verified substitute offering identical electrical specifications but differs in packaging format (tube versus tape-and-reel). Verify that board space accommodates the same 8-SOIC outline. No functional changes are expected between these suffixes regarding performance characteristics.
