LT3495BEDDB#TRMPBF

Overview

The LT3495BEDDB#TRMPBF is a micropower low noise boost converter manufactured by Analog Devices Inc. It provides an output current of 650mA or 350mA depending on the operating mode and features an integrated output disconnect function for power management. The device operates with an input voltage range starting from 2.7V, making it suitable for single-cell lithium-ion battery applications. It utilizes a fixed 1.2MHz switching frequency to minimize external component size. The IC is housed in an 8-lead DFN package designed for space-constrained designs.

Feature Summary

• Integrated output disconnect switch enables complete load isolation during shutdown to minimize quiescent current consumption
• Low noise architecture minimizes output ripple and electromagnetic interference for sensitive analog circuits
• Micropower operation ensures extended battery life in portable devices through optimized standby currents

Applications

• Single-cell lithium-ion battery powered systems requiring efficient step-up conversion
• Portable medical devices needing low noise power supplies for signal integrity
• Wireless communication modules requiring high efficiency boost regulation

Procurement Notes

Verify the specific suffix BEDDB corresponds to the 8-DFN package variant when sourcing. Confirm RoHS compliance status via the manufacturer's material declaration document prior to integration. Ensure the ordering part number matches the exact pinout and thermal pad requirements specified in the official datasheet to prevent compatibility issues with existing PCB footprints.

Selection Notes

Select this component when designing systems that require both high efficiency and ultra-low noise performance from a single-cell source. The built-in output disconnect feature distinguishes it from standard boost converters by allowing true zero-load current states. Consider the 1.2MHz frequency trade-off between component size and EMI filtering requirements for your specific application environment.

Part Context

This part belongs to the LT3495 family of micropower boost converters from Linear Technology, now part of Analog Devices Inc. The series is characterized by its ability to operate efficiently at very low input voltages while maintaining stable output regulation. The BEDDB suffix indicates a specific tape and reel packaging configuration for automated assembly processes.

Replacement Considerations

LT3495AEDDB#TRMPBF offers similar specifications with potential minor electrical parameter variations. LTC3429ES6#PBF is a synchronous alternative but differs in topology and package type. Verify pin compatibility and control loop stability before substituting any other boost converter ICs.
