LT3495EDDB#TRMPBF

Overview

The LT3495EDDB#TRMPBF is a synchronous boost DC/DC converter manufactured by Analog Devices Inc. It integrates a high-efficiency power switch and operates with an input voltage range of 2.7V to 16V, delivering up to 650mA of output current. The device utilizes a fixed 1.2MHz switching frequency to minimize external component size. Key features include an output disconnect function for battery preservation, internal soft-start limiting inrush current, and comprehensive protection against over-current and thermal overload. It is housed in an 8-lead DFN package.

Feature Summary

• Integrates a high-efficiency synchronous power switch for optimized energy conversion
• Includes an output disconnect feature to prevent battery drain when the system is off
• Features internal soft-start circuitry to limit initial inrush current during startup
• Provides cycle-by-cycle current limiting and thermal shutdown for robust operation

Applications

• Battery-powered portable electronic devices requiring efficient step-up regulation
• Systems utilizing single-cell lithium-ion or alkaline batteries
• Applications necessitating minimal standby current consumption
• Space-constrained designs requiring small passive component footprints

Procurement Notes

Verify the specific suffix and tape-and-reel packaging configuration against official Analog Devices documentation prior to ordering. Confirm that the requested quantity aligns with standard manufacturing reel sizes. Ensure compatibility with surface-mount assembly processes suitable for the DFN package type. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Selection Notes

Select this component for applications requiring a compact solution for boosting low input voltages to higher levels. The fixed 1.2MHz frequency allows for the use of small inductors and capacitors, reducing overall board space. Consider the output disconnect capability if maintaining battery life during storage or shutdown is critical. Evaluate the thermal performance requirements relative to the expected load current and ambient temperature conditions.
