LTC3225EDDB#TRPBF

Power Management - Specialized Overview

The LTC3225EDDB#TRPBF is a micropower synchronous step-up DC/DC converter manufactured by Analog Devices Inc. It operates with an input voltage range of 0.7 V to 4.5 V and provides a fixed output voltage of 3.3 V. The device delivers up to 150 mA of output current while maintaining low quiescent current consumption. It features a compact DFN-8 package suitable for space-constrained designs.

Power Management - Specialized Feature Summary

• Synchronous rectification for high efficiency
• Micropower operation with low quiescent current
• Integrated power switch for compact design
• Fixed 3.3 V output voltage option

Power Management - Specialized Applications

• Battery-powered portable electronics
• Wireless sensor nodes
• Medical instrumentation
• Industrial control systems

Power Management - Specialized Procurement Notes

Verify the exact suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the specific voltage variant matches system requirements, as other fixed outputs exist. Check current availability status directly with authorized distributors, as supply levels fluctuate. Ensure compatibility with existing PCB footprints for the DFN-8 package.

Power Management - Specialized Selection Notes

Select this component when a fixed 3.3 V output is required from a single-cell lithium or alkaline battery source. Compare against adjustable variants if flexible output voltages are needed. Consider the 150 mA limit for load requirements. Evaluate thermal performance in enclosed spaces due to the small package size.

Power Management - Specialized Part Context

This part belongs to the LTC3225 family of micropower synchronous boost converters. It shares architectural similarities with other members but differs in output voltage configuration and packaging options. The series is designed for applications requiring minimal standby current and efficient voltage boosting from low-input sources.

Power Management - Specialized Replacement Considerations

Direct substitutes include other LTC3225 variants with different output voltages or packages. Cross-reference with similar micropower boost converters from Analog Devices if pin compatibility is not required. Verify electrical parameters match before substitution.
