LT3973EDD-5#TRPBF

Overview

The LT3973EDD-5#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts an input voltage range from 4.2V to 42V and provides a fixed 5V output at up to 750mA. The device features an adjustable switching frequency ranging from 195kHz to 2.15MHz and consumes only 2.5µA of quiescent current. It operates within a junction temperature range of -40°C to 125°C and utilizes a 10-WFDFN package with an exposed pad for surface mount installation.

Feature Summary

Adjustable frequency operation allows optimization for efficiency or size
Ultra-low quiescent current supports battery-powered applications
Wide input voltage range accommodates various supply sources
Integrated shutdown pin enables power management control

Applications

Battery-powered portable electronics
Industrial control systems
Automotive infotainment and instrumentation
Point-of-load regulation modules

Procurement Notes

Verify the suffix #TRPBF indicates tape-and-reel packaging distinct from tube variants. Confirm the EDD designation corresponds to the specific thermal and electrical characteristics required for your PCB layout. Ensure compatibility with the 10-WFDFN footprint dimensions during procurement planning.

Selection Notes

Select this part when a fixed 5V output is required from wide-range inputs. Consider the 750mA limit against peak load demands. Evaluate the need for adjustable frequency to minimize external component size. Verify thermal performance requirements given the exposed pad design for heat dissipation.

Part Context

This component belongs to the LT3973 family of high-efficiency buck regulators. It shares core architecture with variants like LT3973IDD and LT3973HDD but differs in output configuration and package type. The series is designed for applications requiring low standby current and flexible switching frequency settings across automotive and industrial environments.
