LT1956EFE-5#TRPBF

Overview

The LT1956EFE-5#TRPBF is a monolithic buck switching regulator from Analog Devices, featuring an integrated high-efficiency 1.5A power switch. It operates with an input voltage range of 5.5V to 60V and provides a fixed 5V output. The device utilizes a 500kHz current-mode architecture for fast transient response and loop stability. It is housed in a 16-pin TSSOP package with an exposed pad (EP) for thermal management.

Feature Summary

• Integrates a high-efficiency 1.5A power switch within the die
• Employs current-mode control architecture for stable operation
• Includes internal oscillator, control logic, and protection circuits

Applications

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

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation. Ensure the 16-TSSOP-EP footprint matches your PCB layout requirements before finalizing procurement decisions.

Selection Notes

Select this component for applications requiring wide input voltage ranges up to 60V. The fixed 5V output simplifies design compared to adjustable variants. Consider the 16-pin TSSOP-EP package for its balance of pin count and thermal dissipation capabilities in space-constrained designs.

Part Context

This part belongs to the LT1956 series of high-voltage step-down regulators. It shares architectural similarities with other members like the LT1956IGN-5 but differs in package type and reel configuration. The series is designed for robust performance in demanding environments.

Replacement Considerations

LT1956EFE-5#PBF offers the same electrical specifications in tube packaging instead of tape-and-reel.
