LT3495EDDB-1#TRMPBF

Overview

The LT3495EDDB-1#TRMPBF is a micropower synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 0.7V to 5.5V and provides a regulated output current up to 650mA. The device integrates a 0.2Ω N-channel power switch and supports adjustable switching frequencies from 500kHz to 2.2MHz. It features a low quiescent current of 80µA and includes programmable soft-start, cycle-by-cycle current limiting, and thermal shutdown protection. The component is housed in an 8-lead DFN package.

Feature Summary

• Integrates a high-efficiency synchronous rectifier architecture for improved performance at light loads
• Supports wide input voltage ranges suitable for single-cell lithium-ion or alkaline battery applications
• Includes built-in protection mechanisms such as thermal shutdown and cycle-by-cycle current limiting

Applications

• Portable consumer electronics powered by single-cell batteries
• Wireless sensor nodes requiring low standby current
• USB-powered peripheral devices needing voltage boosting

Procurement Notes

Verify the exact suffix #TRMPBF against official Analog Devices documentation to confirm tape-and-reel packaging and lead-free status. Ensure compatibility with your PCB footprint specifications for the 8-DFN package. Cross-reference the part number with authorized distributors to confirm current availability and authenticity, as supply chain statuses may vary.

Selection Notes

Select this component when designing circuits that require efficient voltage boosting from low-voltage sources like single-cell Li-Ion batteries. Consider the 650mA output capability and the ability to adjust switching frequency for EMI optimization. Evaluate the need for synchronous rectification versus non-synchronous alternatives based on efficiency requirements at specific load currents.

Part Context

This part belongs to the LT3495 family of micropower synchronous boost converters designed for space-constrained portable applications. It shares architectural similarities with other members of the series but is distinguished by its specific pinout configuration and internal feedback network settings defined by the -1 suffix.

Replacement Considerations

LT3495EDDB#TRPBF: Non-micropower variant with similar functionality but different power consumption characteristics.
