LT3485EDD-1#PBF

Power Management - Specialized Overview

The LT3485EDD-1#PBF is a photoflash capacitor charger IC from Analog Devices, housed in a 10-pin DFN package. It operates within an input voltage range of 1.7 V to 10 V and delivers an output current of 400 mA. The device features a flyback topology with adjustable switching frequency and includes an integrated IGBT driver. It supports shutdown functionality and maintains operation across temperatures from -40°C to +85°C.

Power Management - Specialized Feature Summary

• Integrated IGBT driver for direct control of flash tubes
• Built-in voltage output monitor for precise capacitor charging
• Supports compact transformer designs for space-constrained applications

Power Management - Specialized Applications

• Photoflash capacitor charging
• Xenon flash tube driving

Power Management - Specialized Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the manufacturer is Analog Devices Inc., formerly Linear Technology. Ensure the DFN-10 package matches your PCB footprint requirements. Check for obsolescence status as supply may be restricted.

Power Management - Specialized Selection Notes

Select this component for applications requiring integrated IGBT drive capabilities alongside photoflash charging. Compare against the LT3485EDD-3#PBF variant if a fixed 10 V output is preferred over the adjustable configuration. Consider the 400 mA output current limit relative to load requirements.

Power Management - Specialized Part Context

This part belongs to the LT3485 family of highly integrated photoflash chargers. These ICs combine complete charger and IGBT drive functions into a single solution. The family utilizes patented control techniques to optimize performance while minimizing external component count.

Power Management - Specialized Replacement Considerations

LT3485EDD-3#PBF offers similar integration but provides a fixed 10 V output instead of adjustable settings.
