LT3484EDCB-1#TRMPBF

Power Management - Specialized Overview

The LT3484EDCB-1#TRMPBF is a photoflash capacitor charger switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 1.8 V to 16 V and delivers up to 1 A output current through a single output channel. The device functions in temperatures from -40°C to +85°C and utilizes a DFN-6 surface-mount package. Its quiescent supply current is specified at 5 mA, classifying it as a PMIC for power management applications.

Power Management - Specialized Feature Summary

• Integrated high-voltage boost converter architecture designed specifically for charging flash capacitors
• Operates directly from low-voltage sources including single-cell lithium-ion batteries or dual alkaline cells
• Includes internal circuitry for monitoring charge status and controlling external FETs

Power Management - Specialized Applications

• Camera module photoflash systems
• Mobile phone camera flash circuits
• Portable digital imaging devices requiring high-voltage capacitor charging

Power Management - Specialized Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging with partial reel quantities when sourcing. Confirm RoHS compliance status via the manufacturer's official documentation. Ensure the DFN-6 footprint matches your PCB design constraints. Check for any recent lifecycle notifications regarding obsolescence or last-time buy dates.

Power Management - Specialized Selection Notes

Select this component when designing compact flash circuits requiring high efficiency from low input voltages. The DFN-6 package suits space-constrained mobile designs. Compare against the LT3484EDCB-0 variant if different pin configurations are required. Ensure the application supports the maximum input voltage rating of 16 V.

Power Management - Specialized Part Context

This part belongs to the LT3484 family of dedicated photoflash chargers. It shares core functionality with variants like LT3484EDCB-0 and LT3484EDCB-2, differing primarily in package options or minor configuration details.
