LT1680ISW#TRPBF

Overview

The LT1680ISW#TRPBF is a high-power, current-mode switching power supply controller optimized for boost topologies. It drives an N-channel MOSFET switch to provide positive output step-up or step-up/step-down DC-DC conversion. The device operates within an input voltage range of 4V to 60V and supports a maximum duty cycle of 90%. It features clock synchronization capabilities and functions as a single-output phase regulator. The IC is housed in a 16-SOIC package and requires a supply voltage between 9V and 60V.

Feature Summary

Optimized for high-power boost converter applications using current-mode control
Capable of driving external N-channel MOSFET switches for efficient power handling
Includes clock synchronization functionality for noise reduction and multi-phase operation

Applications

Boost converter designs requiring high power density
Forward converter regulators with positive output step-up requirements
Step-up/step-down DC-DC controller circuits

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging with lead-free (PbF) compliance when ordering. Confirm that the 16-SOIC package dimensions match your PCB footprint requirements. Ensure the supplier provides official Analog Devices documentation to validate the component's authenticity and RoHS3 status before final procurement.

Selection Notes

Select this controller for applications demanding high-power boost conversion with precise current-mode regulation. It is suitable where input voltages range up to 60V and external N-channel MOSFETs are preferred for efficiency. Consider the 16-SOIC package size and the requirement for an external driver stage when designing the power stage layout.

Part Context

This component belongs to the LT1680 family of high-power DC/DC controllers from Analog Devices. It is distinct from the LT1681, which is a synchronous forward controller in a 20-pin package. The ISW variant specifically denotes the wide-body SOIC package version designed for higher thermal performance and ease of assembly compared to standard narrow packages.
