LTC3104IMSE#TRPBF

Overview

The LTC3104IMSE#TRPBF is a high-efficiency monolithic synchronous step-down DC/DC converter manufactured by Analog Devices Inc. It operates within an input voltage range of 2.5V to 15V and delivers up to 300mA of output current. The device integrates a 1.2MHz switching frequency architecture with ultralow quiescent current of 2.6µA. Additionally, it includes a separate adjustable 10mA LDO for powering noise-sensitive circuits. The component is housed in a 16-lead MSOP package with exposed pad.

Feature Summary

• Integrates a 300mA synchronous buck converter with a dedicated 10mA low-dropout regulator
• Achieves high efficiency through synchronous rectification technology
• Maintains ultralow quiescent current consumption during operation
• Supports wide input voltage ranges suitable for battery-powered applications

Applications

• Battery-powered portable electronic devices
• Systems requiring noise-sensitive analog circuit power supplies
• Industrial control modules with varying input voltages
• Telecommunications equipment power management

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm RoHS compliance status matches project requirements. Ensure the 16-MSOP package dimensions align with PCB footprint specifications. Validate that the integrated LDO meets the noise performance needs of sensitive loads.

Selection Notes

Select this component when both a main power rail and a clean auxiliary supply are required from a single IC. The wide input range accommodates various battery chemistries. The fixed 1.2MHz frequency allows for compact external component selection. Consider thermal dissipation requirements given the 300mA output capability in the small package.

Part Context

This part belongs to the LTC3104 family of power management ICs designed for space-constrained applications. It combines primary regulation with secondary linear regulation to simplify board layout. The IMSE designation specifies the industrial temperature range and MSOP package variant.
