LTC1628IG-SYNC#TRPBF

DC DC Switching Controllers Overview

The LTC1628IG-SYNC#TRPBF is a high-performance dual step-down switching regulator controller from Analog Devices. It drives all N-channel synchronous power MOSFET stages using a constant frequency current mode architecture. The device supports a switchable frequency range of 150 kHz to 300 kHz, which can be externally synchronized or phase-shifted. It features an input voltage range of 3.5 V to 36 V and provides two independent outputs with remote sensing capabilities for improved load regulation.

DC DC Switching Controllers Feature Summary

• Dual channel control for independent synchronous buck applications
• Constant frequency current mode architecture for stable operation
• External synchronization capability with adjustable phase shift
• Remote voltage sensing for precise output regulation

DC DC Switching Controllers Applications

• Telecommunications infrastructure power supplies
• Industrial equipment power distribution
• Networking and data communication systems
• Point-of-load conversion modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'SYNC' indicates the standard package variant rather than a specialized industrial grade when cross-referencing with distributor catalogs. Confirm that the tape and reel packaging matches the TRPBF designation in procurement orders. Ensure compatibility with external MOSFET selection based on the specified drive current capabilities.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring dual isolated outputs from a single controller IC. The wide input voltage range accommodates various bus voltages common in industrial environments. Consider the thermal performance of the SSOP-16 package relative to the total power dissipation of the control circuitry.

DC DC Switching Controllers Part Context

This part belongs to the LTC1628 family of dual synchronous buck controllers. It is designed to replace older discrete solutions or single-channel controllers by integrating two complete control loops into a single compact package. The SYNC variant typically denotes the standard commercial temperature range and package configuration available through major distributors.
