LT3485EDD-1#TRPBF

Power Management - Specialized Overview

The LT3485EDD-1#TRPBF is a photoflash capacitor charger IC from Analog Devices, housed in a 10-pin DFN package. It operates with an input voltage range of 1.8 V to 10 V and delivers up to 1.5 A output current at a fixed 10 V output. The device features adjustable switching frequency, 1 uA quiescent current, and -40°C to +85°C operating temperature. It integrates IGBT drive functions and includes output voltage monitoring capabilities.

Power Management - Specialized Feature Summary

• Integrates complete charger and IGBT drive functions for photoflash applications
• Includes internal output voltage monitoring for precise control
• Supports adjustable switching frequency for design flexibility
• Features low static current consumption for battery efficiency

Power Management - Specialized Applications

• Photoflash capacitor charging in mobile devices
• Xenon flash systems with integrated IGBT drive
• Portable camera modules requiring compact power management

Power Management - Specialized Procurement Notes

Verify the exact part number suffix #TRPBF indicates tape-and-reel packaging. Confirm RoHS compliance status through official Analog Devices documentation. Ensure the supplier provides valid traceability data. Cross-reference the manufacturer part number with official distributors to avoid counterfeit components. Check for any specific handling requirements during procurement.

Power Management - Specialized Selection Notes

Select this component when integrated IGBT drive and output voltage monitoring are required. The 10V fixed output suits standard photoflash capacitors. Consider the 1.5A current limit for capacitor sizing. The adjustable frequency allows optimization for efficiency or size. Verify compatibility with the system's input voltage range of 1.8V to 10V.

Power Management - Specialized Part Context

Part of the LT3485 family of highly integrated photoflash chargers. The LT3485 series combines charger control and IGBT drive in a single IC. Different suffixes denote variations in monitoring features and packaging. This specific variant includes output voltage monitoring functionality.

Power Management - Specialized Replacement Considerations

LT3485EDD-3#TRPBF offers similar functionality but lacks output voltage monitoring. LT3485EDD-0#TRPBF also omits monitoring features. Direct pin-to-pin replacements within the LT3485 family require verification of monitoring requirements. Consult Analog Devices for qualified alternatives if monitoring is not needed.
