LTC3104IMSE#PBF

Overview

The LTC3104IMSE#PBF is a high-efficiency, monolithic synchronous step-down converter manufactured by Analog Devices Inc. It utilizes a current mode architecture to deliver up to 300mA of output current. The device integrates an adjustable 10mA Low Dropout (LDO) regulator for powering noise-sensitive circuits. It operates with an input voltage range of 2.5V to 15V and features ultralow quiescent current of 2.6µA. Synchronous rectification provides efficiency up to 95%. The component is housed in a 16-TFSOP package with an exposed pad and supports surface mount installation.

Feature Summary

• Integrates a synchronous buck converter with a dedicated adjustable 10mA LDO for low-noise applications
• Achieves high efficiency up to 95% through synchronous rectification technology
• Features ultralow quiescent current consumption of 2.6µA for extended battery life
• Supports wide input voltage operation from 2.5V to 15V

Applications

• Portable devices requiring efficient power management from single-cell lithium batteries
• Systems needing isolated low-noise power rails for sensitive analog or RF circuits
• Battery-operated equipment where minimizing standby current is critical
• Industrial control modules operating within wide input voltage ranges

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence before procurement. Confirm the 16-TFSOP package dimensions match your PCB footprint design. Ensure the supplier provides valid traceability documentation for this Analog Devices component. Cross-reference the manufacturer part number directly with official Analog Devices channels to avoid counterfeit risks.

Selection Notes

Select this component when a compact solution is needed for converting higher voltages down to lower levels with minimal noise. The integrated LDO simplifies designs requiring separate clean power domains without additional external regulators. Consider the 300mA output limit against peak load requirements. The wide input range accommodates various battery chemistries and supply sources effectively.

Part Context

This part belongs to the LTC3104 series of power management ICs from Analog Devices. It is designed as a complete power solution for portable electronics. The series emphasizes efficiency and low noise in a small form factor. It complements other PMIC offerings by providing both switching regulation and linear regulation in one package.

Replacement Considerations

Check for direct pin-compatible alternatives within the Analog Devices portfolio that offer similar current ratings. Verify if newer revisions of the LTC3104 exist with updated packaging or enhanced thermal performance. Ensure any substitute maintains the same 16-TFSOP outline and electrical characteristics for seamless integration.
