LT3653EDCB#TRMPBF

Overview

The LT3653EDCB#TRMPBF is a high-voltage step-down switching regulator manufactured by Analog Devices Inc. It integrates a 1.2A power switch and operates with input voltages ranging from 7.5V to 30V. The device provides an adjustable output voltage down to 0.8V and includes programmable current limit and soft-start features. Packaged in an 8-lead HVSON, it supports continuous operation up to 125°C.

Feature Summary

• Integrates a high-voltage 1.2A power switch for efficient buck conversion
• Includes programmable output current limit protection
• Features integrated soft-start capability to manage inrush current

Applications

• Battery charger applications
• High-voltage point-of-load regulation
• Industrial control systems

Procurement Notes

Verify the specific suffix TRMPBF indicates tape-and-reel packaging when sourcing. Confirm the EDCB package variant matches design requirements. Check official distributor channels for current availability as supply may be restricted. Ensure RoHS compliance documentation is obtained prior to procurement.

Selection Notes

Select this component for designs requiring high input voltage tolerance with moderate output current. The integrated switch eliminates external MOSFETs. Verify thermal performance within the HVSON package for the target load. Ensure the required output voltage range falls within the controller's adjustment capabilities.

Part Context

This part belongs to the LT3653 family of high-voltage synchronous buck regulators. It is designed specifically for battery charging and high-voltage DC-DC conversion tasks. The series emphasizes compact solutions by integrating power switches and control logic into a small footprint.

Replacement Considerations
