LT1765EFE-5#TRPBF

Overview

The LT1765EFE-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc., housed in a TSSOP-EP-16 surface-mount package. It operates with an input voltage range of 3 V to 25 V and provides a fixed output voltage of 5 V. The device supports an output current of 2.4 A and utilizes a fixed switching frequency of 1.25 MHz. Quiescent current is specified at 15 uA, with a maximum operating temperature of +125 C.

Feature Summary

• Integrates a high-speed power switch for efficient step-down conversion
• Features low quiescent current operation for improved efficiency
• Includes thermal shutdown protection for system reliability

Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring wide input ranges
• Industrial control power distribution

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing components. Confirm that the -5 designation corresponds to the fixed 5 V output variant required for the design. Ensure compatibility with the TSSOP-EP-16 footprint during PCB layout verification.

Selection Notes

Select this component for applications requiring a compact solution with a wide input voltage range up to 25 V. The fixed 1.25 MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Verify that the 2.4 A output capability meets the load requirements under expected thermal conditions.

Part Context

This part belongs to the LT1765 family of high-efficiency monolithic buck converters. The series is designed for space-constrained applications requiring fast transient response. The -EFE-5 suffix specifies the fixed 5 V output version within the broader product line.

Replacement Considerations

LT1765EFE-5#PBF is the tube-packaged equivalent of this component.
