Overview
The LT3514IFE#TRPBF is a triple step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.2V to 36V and provides three adjustable positive outputs. The primary output supports up to 2A, while the secondary outputs support up to 1A each. The device features a switch frequency range from 270kHz to 2.1MHz and includes a shutdown function. It is housed in a 24-TSSOP package with an exposed pad and is rated for operation between -40°C and 125°C.
Feature Summary
- Integrates three independent buck converters within a single compact package
- Supports 100% duty cycle operation for minimal dropout voltage
- Features adjustable switching frequency to optimize efficiency and component size
- Includes internal compensation and soft-start circuitry
Applications
- Industrial systems requiring multiple regulated voltage rails
- Automotive electronics power distribution
- Telecommunications infrastructure equipment
- Portable devices with high current demands
Procurement Notes
Verify the suffix TRPBF indicates tape and reel packaging when ordering. Confirm the specific pinout and thermal requirements match your PCB layout design. Ensure compatibility with the required input voltage levels and load currents before finalizing procurement specifications.
Selection Notes
Select this component when multiple isolated or non-isolated low-voltage rails are needed from a higher voltage source. Consider the thermal performance of the 24-TSSOP package under full load conditions. Evaluate the external component count reduction benefits against board space constraints.
Part Context
This part belongs to the LT3514 family of triple buck regulators. It shares functional similarities with other multi-output PMICs but distinguishes itself through its wide input voltage range and high current capability per channel. It serves as a centralized power solution for complex electronic systems.
Replacement Considerations
LT3514IFE#PBF is the tube-packaged equivalent of this component.
