LT1934EDCB#TRPBF

Overview

The LT1934EDCB#TRPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal power switch and operates within a wide input voltage range of 3.2V to 34V. The device maintains a quiescent current of 12μA and includes a zero current shutdown mode that disconnects the load from the input source. It utilizes Burst Mode operation for efficiency optimization at light loads. The component is housed in a low profile ThinSOT package with dimensions of 2mm x 3mm and a height of 0.80mm.

Feature Summary

• Integrates a high-efficiency internal power switch for compact design
• Features Burst Mode operation to minimize power consumption during light load conditions
• Includes a zero current shutdown mode to isolate the load and extend battery life
• Supports regulation from diverse power sources including batteries and logic rails

Applications

• Battery-powered portable electronics
• Systems requiring regulation from 4-cell alkaline batteries
• Power management for 5V logic rails
• Applications utilizing unregulated wall transformers
• Lead-acid battery powered systems

Procurement Notes

Verify the specific suffix and packaging configuration against official Analog Devices documentation to ensure compatibility with your assembly process. Confirm RoHS compliance status as datasheets may indicate variations based on manufacturing lot or region. Cross-reference the exact part number with authorized distributors to validate current availability and lead times, as supply chain statuses change frequently.

Selection Notes

Select this component when designing circuits that require efficient power conversion from varying input voltages while maintaining minimal standby current. The wide input range accommodates multiple battery chemistries and unregulated sources. Ensure the application benefits from the low-profile package constraints and that the internal switch current capability meets the peak load requirements without external components.

Part Context

This part belongs to the LT1934 family of micropower switching regulators designed for space-constrained applications. The series emphasizes low quiescent current and high efficiency across a broad load range. The specific model variant indicates the package type and reel packaging format intended for surface-mount assembly processes.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Generic replacements may not match the specific quiescent current or shutdown characteristics required for sensitive battery applications.
