LTC1929CG#TRPBF

DC DC Switching Controllers Overview

The LTC1929CG#TRPBF is a two-phase, high-efficiency synchronous step-down switching regulator controller manufactured by Analog Devices Inc. It operates within an input voltage range of 4V to 36V and supports a fixed switching frequency adjustable between 150kHz and 300kHz. The device utilizes current-mode control to ensure precise phase current sharing and features a true remote sensing differential amplifier for improved load regulation. It includes internal OPTI-LOOP compensation to enhance transient response and offers a 99% maximum duty cycle for very low dropout operation.

DC DC Switching Controllers Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary by revision. Ensure the operating temperature range meets system requirements. Check for automotive grade variants if harsh environments are involved. Validate pinout compatibility with existing PCB layouts before procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring two-phase interleaving to minimize input ripple. Consider the 4V to 36V input range for versatile supply options. Evaluate the need for remote sensing to compensate for trace resistance. Assess thermal management needs based on the SSOP-28 package limitations. Compare against single-phase controllers if phase count is not critical.

DC DC Switching Controllers Part Context

This part belongs to the LTC1929 series of synchronous buck regulators. It is designed for applications demanding high efficiency and compact solution size. The controller manages external MOSFETs to create a robust DC-DC conversion stage. It is commonly used in industrial and computing equipment where power density is important.

DC DC Switching Controllers Replacement Considerations

Check for direct pin-compatible upgrades within the same family. Verify if newer revisions offer improved thermal performance or updated packaging. Ensure substitute parts support the same 150kHz to 300kHz frequency range. Confirm that alternative controllers provide similar current sharing capabilities.
