Overview
The LT1374HVIFE#PBF is a monolithic buck switching regulator from Analog Devices, housed in a 16-pin TSSOP-EP package. It operates with an input voltage range of 5V to 32V and delivers up to 4.5A of switch current at a fixed 500kHz frequency. The device features an adjustable output voltage capability, typically ranging from 2.42V to 27.52V. Key electrical parameters include a maximum operating junction temperature of 125°C, a minimum of -40°C, and a quiescent current of 20µA.
Feature Summary
- Integrates a high-efficiency synchronous buck topology within a compact surface-mount package.
- Maintains constant 500kHz switching frequency for consistent performance across load variations.
- Includes thermal pad design to enhance heat dissipation and reliability under high power loads.
Applications
- Point-of-load regulation for industrial control systems
- Power supply stages for embedded computing modules
- Battery-powered equipment requiring efficient step-down conversion
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions meet moisture sensitivity level standards to prevent package damage during soldering processes.
Selection Notes
Select this part when a high-current buck converter is required with a wide input voltage range up to 32V. The 16-pin TSSOP-EP package is suitable for designs needing robust thermal management. Consider the 500kHz frequency trade-off between component size and electromagnetic interference when designing the external filter network.
Part Context
This component belongs to the LT1374 family of high-performance switching regulators. It shares architectural similarities with other members like the LT1374CR but differs in package type and voltage handling capabilities. The HV designation indicates enhanced high-voltage tolerance compared to standard variants within the same product line.
Replacement Considerations
LT1374HVIFE#TRPBF serves as a tape-and-reel alternative offering identical electrical specifications and functionality. Verify that the change in packaging format aligns with automated assembly requirements without affecting circuit performance.
