LT3495BEDDB-1#TRMPBF

Overview

The LT3495BEDDB-1#TRMPBF is a micropower synchronous boost converter manufactured by Analog Devices Inc. It operates with an input voltage range of 0.8V to 5V and delivers up to 200mA output current. The device features a fixed 650kHz switching frequency, a maximum output voltage of 40V, and ultra-low quiescent current of 60µA. Packaged in a 10-lead DFN, it supports operation from -40°C to +125°C.

Feature Summary

• Micropower synchronous boost topology for high efficiency at low currents
• Integrated 650mA switch capable of driving external components
• Ultra-low shutdown current minimizes battery drain in standby modes
• Fixed-frequency operation simplifies external component selection

Applications

• Battery-powered portable electronics requiring extended runtime
• Single-cell lithium-ion or alkaline battery boost applications
• Wireless sensor nodes and IoT devices
• Medical instrumentation powered by small form-factor batteries

Procurement Notes

Verify the specific suffix '-1' against official Analog Devices documentation to confirm pinout or functional variations. Confirm RoHS compliance status via the manufacturer datasheet. Check current availability as distribution channels may list limited stock or end-of-life status. Ensure the DFN-10 package footprint matches your PCB design requirements before ordering.

Selection Notes

Select this component when input voltages are low (down to 0.8V) and output regulation above 5V is required. The 650kHz frequency allows for smaller inductors compared to lower-frequency alternatives. Verify that the 200mA load requirement fits within the thermal limits of the DFN-10 package under expected ambient conditions.

Part Context

This part belongs to the LT3495 family of micropower synchronous boost converters designed for space-constrained, battery-operated systems. It integrates a power switch and control logic to minimize external component count. The DFN-10 package provides efficient thermal dissipation while maintaining a small board footprint suitable for modern handheld devices.

Replacement Considerations

Consult Analog Devices technical support for verified cross-reference part numbers. Ensure any substitute maintains the 0.8V minimum input voltage and 650kHz switching frequency. Verify compatibility with the DFN-10 package dimensions and pin configuration.
