LT1956IFE-5#TRPBF

Overview

The LT1956IFE-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It features an input voltage capability up to 60V and provides a fixed 5V output. The device integrates a high-efficiency 1.5A switch, oscillator, control logic, and current mode architecture for fast transient response. Operating at a fixed 500kHz switching frequency, it supports an input range of 12V to 60V with an output current capacity of 1A. The component is housed in a 16-pin TSSOP package with an exposed pad.

Feature Summary

• Integrates a high-efficiency 1.5A power switch within the die
• Utilizes current mode architecture for improved loop stability
• Includes complete oscillator and control circuitry on-chip

Applications

• Industrial point-of-load regulation
• Distributed power systems
• Automotive electronics

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging and lead-free compliance when sourcing. Confirm the manufacturer part number matches exactly to ensure correct pinout and electrical characteristics. Check official distributor listings for current availability status as supply may be limited or subject to allocation.

Selection Notes

Select this component for applications requiring high-voltage input handling up to 60V with a fixed 5V output. The integrated 1.5A switch suits moderate load requirements without external passives. Ensure the 500kHz frequency aligns with EMI constraints and inductor size limitations in the target design.

Part Context

This part belongs to the LT1956 series of high-voltage step-down switching regulators from Analog Devices. The series is designed for robust performance in demanding environments. The LT1956EFE-5 variant shares similar electrical specifications but differs in package type, offering flexibility for various board layout requirements.

Replacement Considerations
