LT8618CAV#TRPBF

Overview

The LT8618CAV#TRPBF is a synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3.2 V to 42 V and provides a fixed output of 5 V. The device delivers up to 100 mA of output current through a single channel. It features an adjustable switching frequency ranging from 200 kHz to 2.2 MHz. The component functions within a junction temperature range of -40°C to 125°C and utilizes a 12-lead LQFN package.

Feature Summary

Integrates high-side and low-side N-channel power switches for synchronous rectification
Supports external synchronization to an internal clock or an external timing signal
Includes programmable soft-start capability to limit inrush current during startup

Applications

Industrial control systems requiring isolated power rails
Automotive electronics operating on 12V or 24V bus architectures
Distributed power supply architectures in communication equipment

Procurement Notes

Verify the specific suffix against official manufacturer documentation to confirm pinout compatibility and thermal characteristics. Ensure that the ordering information matches the required package variant and temperature grade. Cross-reference datasheet revision history to validate electrical specifications prior to integration into final designs.

Selection Notes

Select this component when a fixed 5V output is required from a wide input voltage range up to 42V. Consider the 100mA load capacity and the availability of the LQFN package for space-constrained layouts. Evaluate the need for external synchronization if noise immunity is critical in the target application environment.

Part Context

This part belongs to the LT8618 family of high-efficiency synchronous buck regulators. The series is designed for applications demanding small solution size and high performance. The CAV suffix indicates specific packaging and temperature rating variations within the broader product line managed by Analog Devices.
