DC DC Switching Controllers datasheet and documents for LTC3829IFE#TRPBF

LTC3829IFE#TRPBF

DC DC Switching Controllers Overview

The LTC3829IFE#TRPBF is a synchronous buck DC/DC switching controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 4.5V to 38V and supports a switching frequency between 250kHz and 770kHz. The device features a maximum duty cycle of 94% and includes integrated soft-start, tracking, and current limit control characteristics. Designed for surface mount installation, it utilizes a 38-WFQFN package with an exposed thermal pad (5x7mm). The component supports positive output configuration and functions as a single-output regulator suitable for industrial temperature ranges from -40°C to 125°C.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix and tape-and-reel packaging details against official distributor catalogs before ordering. Confirm that the 38-pin QFN footprint matches the target PCB design requirements. Ensure compatibility with the intended switching frequency settings and thermal management solutions for the operating environment.

DC DC Switching Controllers Selection Notes

Select this controller for designs requiring wide input voltage ranges up to 38V and flexible frequency programming. Consider the thermal performance of the exposed pad package when designing for high-power density applications. Evaluate the need for multi-phase configurations if load currents exceed single-channel capabilities.

DC DC Switching Controllers Part Context

This component belongs to the LTC3829 family of synchronous buck controllers. It is designed to drive external N-channel MOSFETs for efficient step-down conversion. The part is commonly paired with evaluation boards such as the DC1675A for circuit validation and performance testing during the development phase.
