LT1913EDD#TRPBF

Overview

The LT1913EDD#TRPBF is a monolithic synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3.6V to 25V and provides an adjustable output voltage from 0.79V to 24.25V. The device delivers a continuous output current of 3.5A. It features a programmable switching frequency ranging from 230kHz to 2.45MHz, allowing for optimization between efficiency and external component size. The IC is housed in a compact 10-lead WDFN package with an exposed thermal pad, designed for surface-mount installation.

Feature Summary

Integrated high-efficiency synchronous rectification topology
Programmable switching frequency for design flexibility
Compact footprint optimized for space-constrained applications

Applications

Point-of-load regulation for digital signal processors
Power supply systems for embedded industrial controllers
Battery-powered equipment requiring efficient voltage conversion

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm tape-and-reel packaging configuration. Ensure that the ordering part number matches the exact electrical specifications and package variant required for the target application circuit design.

Selection Notes

Evaluate the required output current capacity against the 3.5A limit under expected thermal conditions. Select the appropriate switching frequency to balance magnetic component size against transient response requirements. Confirm that the input voltage range aligns with the source power supply characteristics.

Part Context

This component belongs to the LT1913 family of synchronous buck regulators. It shares architectural similarities with other high-current DC-DC converters from Analog Devices but is distinguished by its specific 3.5A current rating and wide input voltage capability within a small DFN form factor.
