LT1934EDCB#TRMPBF

Overview

The LT1934EDCB#TRMPBF is a micropower step-down DC/DC converter manufactured by Analog Devices Inc. It features an internal 400mA power switch and is housed in a low-profile ThinSOT-6 package measuring 2x3mm with a height of 0.80mm. The device operates within an input voltage range of 4V to 34V, with a nominal input of 10V. It utilizes current-mode control and draws a quiescent current of 12μA. The component includes a zero current shutdown mode that disconnects the load from the input source. It is classified as a switching regulator controller with one functional unit.

Feature Summary

Integrates a 400mA internal power switch for compact design
Features Burst Mode operation for high efficiency at light loads
Includes zero current shutdown mode to disconnect the load
Supports wide input voltage ranges for various power sources

Applications

Battery-powered systems requiring low quiescent current
Regulation of unregulated wall transformers
Power management for lead-acid batteries
5V logic rail regulation

Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status as datasheets may vary by revision or region. Ensure the supplier provides official documentation matching the LT1934EDCB part number to avoid counterfeit components. Check for lead-free availability if required by project specifications.

Selection Notes

Select this component for applications requiring a small footprint and low standby power consumption. The wide input voltage range makes it suitable for diverse power sources. Consider the 400mA output current limit when designing for higher load requirements. The ThinSOT package is ideal for space-constrained portable electronics.

Part Context

The LT1934 belongs to Analog Devices' family of micropower step-down switching regulators. It is designed to replace linear regulators in battery-operated applications to extend battery life. The device integrates the power switch and control circuitry into a single small package, reducing external component count and board area.
