LT1934IDCB#TRPBF

Overview

The LT1934IDCB#TRPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal 400mA power switch and operates within a wide input voltage range of 3.2V to 34V. The device provides an adjustable output voltage with a maximum output current of 300mA. Quiescent current is specified at 12μA, supporting efficient battery-powered applications. It utilizes Burst Mode operation for high efficiency at light loads and includes a zero-current shutdown mode. The component is housed in a compact DFN-6 package.

Feature Summary

Integrates a 400mA power switch within a low-profile ThinSOT or DFN package
Supports wide input voltage ranges from alkaline batteries to unregulated wall transformers
Features Burst Mode operation for optimized efficiency under light load conditions
Includes a zero-current shutdown mode to disconnect the load from the input source

Applications

Battery-powered systems requiring extended runtime
5V logic rail regulation
Lead-acid battery powered equipment
Unregulated wall transformer applications

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and temperature rating. Confirm RoHS compliance status as indicated in the datasheet. Ensure availability through authorized channels due to potential supply constraints. Cross-reference the manufacturer part number with distributor listings to validate authenticity and revision history before procurement.

Selection Notes

Select this component for designs requiring a compact footprint and low quiescent current. The wide input range accommodates various power sources without external level shifting. Verify that the required output current does not exceed the internal switch limits. Consider thermal performance in the chosen package when designing for higher ambient temperatures.

Part Context

This part belongs to the LT1934 series of micropower step-down switching regulators. The series is designed for applications where space and power consumption are critical constraints. It serves as a solution for converting higher voltages to lower regulated levels efficiently.
