Overview
The LT1976BIFE#PBF is a synchronous buck switching regulator IC manufactured by Analog Devices Inc. It operates with an input voltage range from 3.3V to 60V and provides an adjustable output voltage between 1.25V and 55.2V. The device delivers a maximum switch current of 1.5A and supports a switching frequency up to 230kHz. It is housed in a 16-lead TSSOP package with an exposed pad for thermal management, suitable for surface-mount applications across a temperature range of -40°C to +125°C.
Feature Summary
- Integrated synchronous rectification architecture for improved efficiency
- Wide input voltage capability supporting high-voltage sources
- Adjustable output voltage via external resistor network
- Thermal performance optimized through exposed pad design
Applications
- Industrial power supply systems
- Distributed point-of-load regulation
- High-voltage battery-powered equipment
- Telecommunications infrastructure power stages
Procurement Notes
Verify the specific suffix BIFE against official Analog Devices documentation to confirm pinout and electrical characteristics match your design requirements. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Confirm RoHS compliance status if required by your assembly process specifications.
Selection Notes
Select this component when designing circuits requiring high input voltages up to 60V with moderate current demands. The synchronous topology makes it suitable for applications prioritizing efficiency over cost compared to non-synchronous alternatives. Consider the 16-TSSOP package constraints regarding PCB real estate and thermal dissipation capabilities during layout planning.
Part Context
This part belongs to the LT1976 family of synchronous buck regulators designed for robust performance in demanding environments. The series offers various package options and fixed/adjustable variants to accommodate diverse system architectures. It serves as a core power management solution for converting higher bus voltages to lower logic or sensor levels efficiently.
Replacement Considerations
LT1976IFE#TRPBF: Verified alternative within the same product family offering identical electrical specifications but supplied in tape-and-reel packaging instead of tube.
