Overview
The LT1371HVISW#PBF is a high-voltage switching regulator from Analog Devices, designed for versatile DC-DC conversion topologies including buck, boost, Cuk, flyback, forward, and SEPIC. It operates with an input voltage range of 2.7 V to 30 V and delivers a switch current of 3 A. The device features a fixed 500 kHz switching frequency and adjustable output voltage starting at 1.245 V. Packaged in a 20-SOIC format, it supports both positive and negative output configurations.
Feature Summary
- Supports multiple converter topologies including buck, boost, Cuk, flyback, forward, and SEPIC
- Capable of generating positive or negative output voltages
- Integrated shutdown control for power management
Applications
- Industrial power supply systems requiring flexible topology options
- Battery-powered equipment utilizing boost or buck-boost configurations
- Telecommunications infrastructure using flyback or forward converters
Procurement Notes
Verify the specific suffix against official documentation to confirm package type and temperature rating. Ensure compatibility with required thermal dissipation methods for the SOIC-20 housing. Cross-reference datasheet revisions to validate pinout consistency before integration into new designs.
Selection Notes
Select this component when design requirements demand a single IC solution for diverse topologies such as SEPIC or Cuk. The 3 A switch current capability suits moderate power applications. Verify that the 500 kHz frequency aligns with external inductor selection constraints and EMI requirements.
Part Context
This part belongs to the LT1371 family of high-efficiency switching regulators. It shares core architecture with variants like LT1371ISW#PBF but differs in voltage handling capabilities. The series is characterized by current-mode control and broad input voltage tolerance suitable for various industrial standards.
Replacement Considerations
LT1371ISW#PBF serves as a direct functional substitute within the same package, though it may have different voltage ratings. LT1370HVIT7#PBF offers similar topology support but utilizes a TO-220-7 package and higher current capacity.
