Overview
The LT1374HVIFE#TRPBF is a monolithic buck switching regulator from Analog Devices, housed in a 16-lead TSSOP package with an exposed pad. It operates with a fixed 500kHz switching frequency and supports an input voltage range of 5V to 32V. The device provides an adjustable output voltage between 2.42V and 27.52V, delivering up to 4.5A of switch current. Key electrical specifications include a typical operating supply current of 2.5mA and a shutdown current of 20µA. It functions within a junction temperature range of -40°C to +125°C.
Feature Summary
- Integrates a high-power 4.5A switch with a constant 500kHz oscillator for reduced external component size.
- Supports both Buck and SEPIC topologies for flexible input-output voltage configurations.
- Features cycle-by-cycle current limiting and a low-power shutdown mode.
Applications
- Industrial point-of-load regulation
- Distributed power systems
- Battery-powered equipment requiring efficient step-down conversion
Procurement Notes
Verify the specific suffix #TRPBF confirms tape-and-reel packaging when ordering. Confirm the HV variant rating matches the system input voltage requirements, as standard versions may have lower limits. Ensure the 16-TSSOP-EP footprint aligns with the PCB layout design. Check for RoHS compliance status if required by project specifications.
Selection Notes
Select this part when a high-current buck converter is needed with a wide input voltage range up to 32V. The 500kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the thermal performance of the TSSOP-EP package for heat dissipation needs. Verify that the adjustable output range covers the target application voltage.
Part Context
This component belongs to the LT1374 family of high-efficiency switching regulators. It shares core architecture with variants like LT1374CR and LT1374IR, differing primarily in package type and maximum input voltage ratings. The HV designation indicates enhanced high-voltage capability suitable for broader industrial applications.
Replacement Considerations
LT1374HVIFE#PBF offers identical electrical characteristics but in tube packaging instead of tape-and-reel. Other family members such as LT1374CR provide similar functionality in a DPAK-7 package with potentially different thermal and voltage constraints.
