LT1976IFE#TRPBF

Overview

The LT1976IFE#TRPBF is a high-voltage synchronous step-down switching regulator 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 continuous switch current of 1.5A at a fixed switching frequency of 200kHz. Packaged in a 16-TSSOP with an exposed pad, it supports junction temperatures from -40°C to +125°C.

Feature Summary

Integrated synchronous rectification for improved efficiency without external Schottky diodes
High input voltage capability up to 60V suitable for industrial power buses
Fixed 200kHz switching frequency allows for compact passive component selection
Adjustable output voltage via external resistor divider

Applications

Industrial point-of-load regulation
Automotive electronics systems
Distributed power architectures
Battery-powered equipment charging

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the 16-TSSOP-EP package dimensions match your PCB footprint requirements. Ensure the supplier source is authorized to guarantee component authenticity and traceability for critical applications.

Selection Notes

Select this component when a wide input voltage range exceeding standard regulators is required. The fixed 200kHz frequency optimizes the trade-off between component size and electromagnetic interference. Verify that the thermal performance of the exposed pad meets the system's heat dissipation needs under maximum load conditions.

Part Context

This part belongs to the LT1976 family of high-voltage synchronous buck converters. It shares core topology with other variants but differs in packaging and shipping configuration. The #TRPBF suffix specifically denotes the tape and reel format intended for automated surface-mount assembly processes.
